"The Case Of The Disappearing Controls" By Cat "SOLVED" www.vbforums.com

I've changed the location of the original image used and even renamed it. But, I deleted the original picture box control and pointed to the new image name and location. That didn't take care of it. And the chart control problem may have originated from renaming the form. But a new chart control added to the renamed form should work! Oh, and I also renamed the chart control. All code is reflecting the renamed controls, form, and images. The problem still persists.CatCorrection: the picture box control does not disappear -- it simply does not load the image. The chart control does disappear.

DataSource Controls :: Count Items Returned From ObjectDataSource? forums.asp.net

Web Forms :: Cannot Get Label On Chart To Display Properly forums.asp.net

I am new to Chart controls and I'm trying to display a label (text) for a datapoint in a chart instead of a value. I'm using the following code to load the datapoints and to add label information for each point (each label will be different). But when the chart is displayed all datapoint labels are blank (if I use the first line of code) or the labels are all the same, containing the last rows value (if I use the 2nd line of code). Can someone tell me what I am doing wrong? Is there something in the .aspx that I need to set? [Code].... For example: I have 3 rows in my grid with the label data: "Cat", "Dog", "Mouse". But the label in my chart is blank for all points when I use the first line of code and when I use the second line of code the label is "Mouse" for all points.

C# - Linear Regression/trend Line With Ms Charting stackoverflow.com

I have data that are numbers both on x and y and have charted them using mschart 4.0 I need to add a trend line/linear regression to a bunch of points I have. The data on x and y are both numbers (no dates anywhere), for instance (33.4,45.1) would be a point. In the samples I downloaded from the first link I found a linear regression sample in the code files forecasting.aspx(.cs), and I found this ms documentation I have added a linear regression line to the chart with the following line (once all other data it setup etc) Chart1.DataManipulator.FinancialFormula(FinancialFormula.Forecasting, parameters, "Input:Y", "Forecasting:Y,Range:Y,Range:Y2"); The problem with both of these is that they assume dates are used. I went ahead and implemented it anyway, but my regression line starts at around the x value of 20, and will go to an x value of the max x value of one of the points (almost 70) if I give the parameter Period a value of 700. But since it doesn't start at x value 0 I don't trust it is correct.

Cannot Change Chart Thickness - Bug? social.msdn.microsoft.com

Conditional Format Chart Data Series Points www.ozgrid.com

Background: I have a Chart sheet with a combination bar/line chart on it. Data is coming from a "datasheet". There is a combo box on the chart sheet that allows you to choose a specific office whose data you want to view. Pick an office from the dropdown and the chart changes. The data is a count of closed cases by month. The data sheet shows 22 Offices with their monthly data, along with entries for each month of the Upper Control Point, Lower Control Point and Mean based on the nationwide data for that month. The chart itself uses bars to show the office's case count per month, and I've incorporated 3 additional data series to plot the UCP, LCP and Mean as lines for each month. I'd like to change the color of the bars to be Blue, Green or Red depending on where they fall in the 3 lines. I sort of have it working, but I'm stuck. The code below grabs the value of each series point and compares it to the 3 control points and does change the colors. I've figured out how to use the If, next to change from one series point to the next, but cannot figure out how to loop through each of the control points. As it stands now, it looks only at the first month's control point and uses that for each successive month. I hope this is clear and I've tried to keep it as short as possible while still providing enough information.

Only Charting Data In Series That Meet Criteria www.xtremevbtalk.com

Am wondering if this can be done. I have two time series in column A and B which I want to chart but only a some data points for Coloumn B. In column C I have two flags - Y and N. Y denotes I want the data point in the B row to included in the chart graph, N means I don't want it charted. Is there a way to get excel to chart all points in column A and only some points in colomn B that have an assocaited Y flag in Column c? For example: Row 1 Y = include point in line chart Row2 N = Don't include the point in line Row3 Y= include point in line chart I know I could use a look up function to filter out the Ns but I don't want to create new chart data series on the sheet - I just want the chart to reference the raw data which will increase over time. Also I know I could use the autofilter to chart each series seprately but not at the same time. Anyone got an ideas? Is there anyway to use an if statement within the chart for a given series? I'm thinking VBA route will only be the way forward. Thanks Excellors........

Forms Data Controls :: Zero For Non-existing Records In Chart? forums.asp.net

specific section for the chart control, sorry if this is in the wrong place.Using Microsoft's chart and a line or fast line type,is there a way to default non-existing values to zero? If for example I have dates on the X axis and have all of January but don't have values on for a couple of days by default the line jumps from one record to nother. Is there a way to make it drop to zero for the date there is no record for?

Custom Function, UDF, To Return Nothing Or Empty Text www.ozgrid.com

I am plotting a chart using data from custom functions. On occasion, the formulas return erratic values (due to the underlying data) which I wish to exclude from the chart. If the function does not pick up a value in the code, by default it returns a zero.I would like when this happens to have my function return nothing instead of a value - and I mean absolutely nothing, not a blank string. in this way, the chart line will totally ignore this point.

Hide Minus Values On Y-axis On A Chart www.mrexcel.com

column chart displaying various pieces of data. At the top of my worksheet I have a combo box which allows you to select a local authority name; and all relevant information in the worksheet is highlighted (using conditional formatting, extra series in charts to make relevant points highlight in red, etc). I've added a series to the chart and changed it's type to line - then with the data labels positioned beneath the points on the line I can get conditional formatted x category labels - all outlined here: [url] Because my x category labels are fairly long I've had to give them an orientation of -90 and make the minimum y-axis value equal to -200 to give enough room beneath the chart to fit the text in. As I said above, the values below 0 are just there to provide space at the bottom of the chart, so my question is: is there a way to hide these negative values? I'm sure I've done it before, but can't remember how - I thought maybe a custom number format of #;[White]# would work, but it just inverted my text (white text on black background).

Formatting X Axis On Scatter Plot Chart www.ozgrid.com

Attached is a chart I am trying to create. So basically, I originally used a line chart but it didn't have the flexibility of the scatter chart, but i am having a very hard time formatting the X axis. First of all - I would like the line in the middle at the 0% point to actually go to the bottom so that the x axis labels aren't in the middle of the graph. Second the x axis labels aren't showing up correctly. They should be quarters: 1Q:02, 2Q:02, 3Q:02, 4Q:02... Finally, how can I show the correlation between these two data points plotted - the R-squared. THANKS!!! Auto Merged Post;I actually was able to figure out most of what I asked. What is remaining: how do I calculate the R-Squared on the chart? Isn't there a way to do it automatically in excel on the chart.

Dataset - Charting Library For Huge Data? stackoverflow.com

Does anyone know of a Javascript charting library that can handle huge datasets? By 'huge', I mean drawing a line graph with around 1,000 lines and 25,000 data points in total. (With an uneven distribution of points per line. A lot of lines have very few points, but some have up to 4,000.) Here is an example data file. Currently I'm using Highcharts, but it's far too slow at plotting the example file. Here is my test website, graphing the example data file using Highcharts. WARNING: Going to that page will eat up your processor for a while :) I don't want to use Flash or Silverlight. I was hoping to use Javascript so that my users can zoom+pan around the graph, and turn lines on/off etc. But if this is just too much data for any Javascript charting library to handle, then I'll have to make the graphs server-side.

Excel 2003 :: Add Horizontal Line To Stock Chart? www.excelforum.com

I am using the the stock chart and I would like there to be a horizontal line across the chart with a y-axis of the opening price. In the end I want this to be in VBA but how to do this manually I should be able to put it in loop of data that will produce many charts with a horizontal line starting at the day opening. I have tried to add a new series to the chart but I'm using the Candle stick stock chart and the new series comes out as a vertical not horizontal line. I read about using a secondary horizontal axis but all the tutorials I find are in Excel 2003 and they donlt line up well with Excel 2007. I found this link on charts with horizontal lines but again they are in 2003 and I'm using a candle stick stock chart not a scatter chart. [URL]

Creating A Circular Profile With VB? www.xtremevbtalk.com

I have tubing material which is circular (360°) Every 4.5° (80 points) I get a reading of how thick the material is.I want to create a circular diagram on my form to show all 80 points and their relative thickness to a setpoint thickness. So you would see a perfect circle representing the setpoint thickness, and around that circle you would see the 80 points showing the actual variance.Where is the best place to start looking at how to piece this together?**This is very similar to a Radar Chart in excel... however the radar chart is too limiting. I need to have the size of the chart relative to a setpoint value which is changing and allows for the setpoint circle of the chart to be a line always at 50% outward from the center of the circle, create the scale and have the circle always the same size.ie: Setpoint thickness of 100microns. This creates a circle with a reference from 0-200 microns from the center to the outer edge. My 80 points of data are then placed around the setpoint line always in the same spot.

How To Select Covered Data Point On A Series In A Chart www.mrexcel.com

At the moment I've got a chart with 3 series lines on it and each line has 12 points. I need to select the 12th point on each series in the chart and create a label for it. The 3 lines are Budget, Forecast and Actual and often the Forecast line hits the same points as the Budget line in the chart and every time I try to find a way to select the last point on the Forecast line, I end up selecting the budget one because it's the one in the foreground. I can select the forecast line with the keyboard arrows, but not the last point. I also try to zoom in to get it but one of my charts has exactly the same forecast line as budget line and I still need the forecast line because the forecast will change in future. I can delete the budget line then add it back, but this is difficult and one I'd have to repeat many times because I'm always making graphs and labelling the final point in a series is something I'm going to have to do more often. How do I select the last point on the forecast line if it's directly behind the budget line?
