Take into account the values of the X axis

145

Hi, I have a datatable that I fill with the following data (example):

Freq VideoValue AudioValue

10 25 14

20 20 12

40 26 11

50 28 15

I want to show the values of Video and Audio for each Frequency. (Freq is on the X Axis, and Video and Audio are the two series to show)

I am able to do that with a ColumnChart (See attachments Infragistics.jpg and Infragistics2.jpg that I got with the property SwapRowsAndColumns set to False and True respectively)

What I want is to scatter the columns according to their values (see attached screenshot Excel2.jpg), something like a time-basis. But these values can be positive or negative.

I don't mind adding columns to my datatable or change the type of chart if needed(as long as it shows bars).

Thanks

Imad

Hello Imad,

Excuse me for the late reply. I have been looking into this for you and thought the FillSceneGraph event is the only way I found to do this I cannot say it will be easy. It is rather doable. If you decide on using this approach I’d be glad to assist you with anything I can.

Kind regards Petar.

Hi, thanks for your response.

Unfortunately, that wouldn't work in my case since the real X values that I am working with are continuous (55.3, 55.9, 65.3, 110.5, etc...) so I can't create dummy data in between.

I will look into using a Scatter Chart instead.

Is there any "easy" way that I change the dots into bars (or boxes)? maybe using the FillSceneGraph event?

Thanks,

Imad

Hello Imad,

I have been looking into your issue and since the Column charts spread their columns equally across their X axis there is no way to make them pinpoint a value on the X Axis like the Scatter chart. In that specific situation when you need to “skip” 30 you can add a dummy data row like this one to make it look as you wanted:

Freq   |   VideoValue      | AudioValue

30         DBNull.Value DBNull.Value

or

30                         0                              0

Hope this helps. Please let me know if you require any further assistance on the matter.

Sincerely,
