Binding Stack Graph

[Adrian]

I'm trying to create a stack bar graph either in code or in data binding which will bind to my data collection.

Data Collection is a list (of question)  with question containing correct, incorrect and skipped totals.

I can't seem to find a good example - any assistance would be great.

Hi,

To achieve this you can create two or more BarSeries(with BarSeries.CombineMode set to Stack), bind their ItemsSource to the property that hold the collection of objects and map the Category and the Value of each point to the properties that hold this information through the CategoryBinding and ValueBinding properties. For your convenience I have attached a project that demonstrates this scenario.

Let me know if this works for you.

Got that working - I'm now trying to set the height of the bars (ultimately the graph) to the a much smaller height.  Its a single stacked bar chart so I really don't need a lot of labels and want the height to be much smaller than its showing at the moment.

Attached file shows I can display 4 items but want to reduce size of bar chart to show 8-10 items.

Hi,

You can control the number of labels through the LinearAxis.LabelInterval property. Also, to make the chart smaller you can change the RadCartesianChart.Height and RadCartesianChart.Width properties. Note, that by default the RadCartesianChart.MinWidth and RadCartesianChart.MinHeight are 100, so if you need smaller values you can change them.

Thanks, I think the MinHeight and Width wee the ones which were causing me the problems.
