C# MSChart - charts area limits

Question

I have one Chart and three ChartArea that are aligned in view, zoom, cursor: this is my related previous post. All things works well except that the three ChartArea are not

Answer 1

Have you tried using the chart area alignment options? I would try something like:

//define inner plot position of the chart areas
dlChart.ChartAreas[0].InnerPlotPosition.Auto = true;
dlChart.ChartAreas[1].InnerPlotPosition.Auto = true;
dlChart.ChartAreas[2].InnerPlotPosition.Auto = true;

//set our second chart area's alignments to match our first chart area
dlChart.ChartAreas[1].AlignmentOrientation = AreaAlignmentOrientations.Vertical;
dlChart.ChartAreas[1].AlignmentStyle = AreaAlignmentStyles.All;
dlChart.ChartAreas[1].AlignWithChartArea = dlChart.ChartAreas[0].Name;

//set our third chart area's alignments to match our first chart area
dlChart.ChartAreas[2].AlignmentOrientation = AreaAlignmentOrientations.Vertical;
dlChart.ChartAreas[2].AlignmentStyle = AreaAlignmentStyles.All;
dlChart.ChartAreas[2].AlignWithChartArea = dlChart.ChartAreas[0].Name;

Answer 2

You may want to take control of the size of the InnerPlotPosition.

(But Baddack's solution is simpler and more flexible!)

Here is an example:

After setting up a Chart with three CharAreas, setting Minima and Maxima as well as adding one DataPoint to each we get this :

Your issue is showing clearly.

After setting the InnerPlotPosition to a fixed percentage it looks like this:

Here is how to set the InnerPlotPosition size:

ca1.InnerPlotPosition = new ElementPosition(10, 5, 80, 90);
ca2.InnerPlotPosition = new ElementPosition(10, 5, 80, 90);
ca3.InnerPlotPosition = new ElementPosition(10, 5, 80, 90);

Note that both ChartArea.Position and ChartArea.InnerPlotPosition are called 'Position' but really are areas of percentages referring to the respective containers!

So my example has a Left distance of 10%, a Top space of 5% and Width of 80% and Height of 90%. Which leaves 10% space at the Bottom and 5% at the Right. Note: All are referring to the ChartAreas not the ClientArea of the Chart! (Which are still at Auto, which maximizes the size.)

This was my initial setup:

ChartArea ca1 = chart.ChartAreas[0];
ChartArea ca2 = chart.ChartAreas[1];
ChartArea ca3 = chart.ChartAreas[2];


Series s1 = chart.Series[0];
Series s2 = chart.Series.Add("Series2");
Series s3 = chart.Series.Add("Series3");

s2.ChartArea = ca2.Name;
s3.ChartArea = ca3.Name;

s1.Points.AddXY(1, 7);
s2.Points.AddXY(1, 777);
s3.Points.AddXY(1, Math.PI);
