Hi.

How do I make a ChartView occupy the entire panel it is contained in?

When I add my ChartView containing the SimpleLinePlot to a panel there is lots of empty space on both sides of the chart, and at the top and bottom.

I have set the Dock to Fill and it resizes properly when I resize the form but the chart is not drawn where it utilizes all of the space available. There is a lot of empty space, especially to the left and right of the chart.

Thanks

We tested our LinePlotSalesVolume example, which is simple graph in a form. While displaying Form1 in the designer, we set the Dock property of the LinePlotSalesVolume control in the form to Fill, and the graph fills the entire form. Running the program, the graph fills the entire form. Resizing the form, and the graph resizes to fill the entire form.

What happens when you do the same ?

When I do that it does put the Sales Volume plot in the center and it does resize properly when I resize the form. However I would not say that the plot fills the available area.
I would say the graph occupies perhaps a total of 60-70% of the actual space available. There is a lot of empty space to the left and right of the chart. Is there any way I can send you a screenshot to illustrate what I mean?

Thanks

We cannot explain why your compiler is acting differently than our own.

Please answer the following questions:

1. What product are you using: QCChart2D for .Net, or QCChart2D CF for .Net Compact Framework?

2. What language are you using: VB or C# ?

3. What compiler revision are you using ? VS 2002, VS 2003 or VS 2005 ?

I just sent two screenshots to support@quinn-curtis.com illustrating what I am seeing.

1. QCChart2D for .Net

2. C#

3. VS 2003


Thanks

What you want is the graph to fill the ChartView, NOT the ChartView UserControl to fill the panel it is placed in. This has nothing to do with the Dock property of the ChartView UserControl, which works exactly as it should, placing the ChartView UserControl with respect to the parent containter

The position and size of the graph in the ChartView is set using the coordinate systems SetGraphBorderDiagonal method, which is used in every example program and described in the manual.

// Original code from LinePlotSalesVolume
TimeCoordinates pTransform1 = new TimeCoordinates();
pTransform1.AutoScale(DatasetArray, ChartObj.AUTOAXES_FAR , ChartObj.AUTOAXES_FAR);
pTransform1.SetGraphBorderDiagonal(0.15, .15, .9, 0.8) ;


If you want the graph larger in the ChartView, define the border with smaller margins.

pTransform1.SetGraphBorderDiagonal(0.075, .1, .95, 0.9) ;
