I am trying to overlay the legend on a 355 x 250 chart using the following code:
oChart.Legend.Overlay=NullableBool.True
oChart.Legend.X = 100
oChart.Legend.Y = 175
However, regardless of the values I set for X and Y, the legend keeps being pushed to the outside of the chart area (see attachment).Any help is appreciated. I'm using Slides 7.4.0.0.
Thanks,
Scott
Hi Scott,
I have observed the requirements specified by you. Actually,
when you set the position of legends in the chart area you need to give X, Y
values from 0 to 1. 0 referring as top left corner of chart area and 1
referring as bottom right corner of the chart area. Whatever position you need
to give within the chart area, you need to map in between 0 and 1 and in
accordance with chart width and height. The following sample code will help you
understand the concept. Please share, if I may help you further in this regard.
PresentationEx pres = new PresentationEx();
SlideEx slide = pres.Slides[0];
int ChartWidth = 400;
int ChartHeight = 400;
ChartEx chart = slide.Shapes.AddChart(ChartTypeEx.ClusteredColumn, 100, 100, ChartWidth, ChartHeight);
float LegendXPosition = 100;
float LegendYPosition = 175;
//The plotting position in chart area is from 0 to 1 w.r.t maximum chart width and height
//So we need to map the desired legend poistion based on this mapping
float newLegendXPosition = (float)(LegendXPosition / ChartWidth);
float newLegendYPosition = (float)(LegendYPosition / ChartHeight);
chart.Legend.X = newLegendXPosition;
chart.Legend.Y = newLegendYPosition;
pres.Save("D:\\Aspose Data\\TestLegend.pptx", Aspose.Slides.Export.SaveFormat.Pptx);
