index out of bounds exception after data bound

[ron.kagan]

Hello. I'm getting very frustrated with this control. I am working with a datatable that is crosstab transformed to a bar chart.

in the databound event i am changing the x axis min and max, which caused the index was outside teh bounds of the array and this stacktrace :

I cannot figure out what i am doing wrong as this sounds something you should be able to do.

Can you post some information about the structure of your data and how you are customizing the crosstab transform to help us duplicate this issue?

JuanC

[ron.kagan]

Sure thing.

My data table consists of two columns - XValue (double) and YValue (int)

here is the code I use

chart1.Gallery = Gallery.Bar;

chart1.ItemsSource = histogramTable.DefaultView;

CrosstabTransform ctt = new CrosstabTransform();

ctt.RowPath = "XValue";

ctt.ValuePath = "YValue";

ctt.XValuePath = "XValue";

chart1.DataTransforms.Clear();

chart1.DataTransforms.Add(ctt);

in the databound event , if this two lines exist, I get the mentioned exception :

chart.AxisX.Min = new DataUnit(_minXValue);

chart.AxisX.Max = new DataUnit(_maxXValue);

If i skip these two lines , the chart appears but with no visible data as the axis is not correct.

if i "refresh" - where i reassign the itemsource to the chart and the lines that sets the axixX min/max are called again, the chart appears as it should

[JuanC]

I don't think you need a crosstab transform in this case, crosstab is not easy to explain in a few lines but I'll try.

ChartFX normally uses columns in your dataset as series to be plotted (e.g. lines in a line chart) and records in your dataset as "points" in the X axis,e.g.

Month - Nokia - RIM - Apple

Jan - 14 - 12 - 9

Feb - 15 - 11 - 10 

So you would create as many series as manufacturers and set their BindingPath properties appropriately, but sometimes your data looks like this

Manufacturer - Month - Sales

Nokia - Jan - 14

RIM - Jan - 12

Apple - Jan - 9

Nokia - Feb - 15

RIM - Feb - 11

Apple - Feb - 10

In this case you would probably want one series per manufacturer and one X point per month so you would use crosstab setting the RowPath as Month and ColumnPath as Manufacturer. Also note that bar charts normally do not support X values as it is not defined how wide should the bars be drawn. Normally XY data should be plotted using Scatter, Line or Area galleries.

If you just want a scatter chart using this data you can create a SeriesAttributes, set its BindingPath and BindingPathX to the names of your Y and X fields and add this SeriesAttributes to the chart's series collection.

The exception you are receiving is probably independent of this, if you know the min and max you want in a particular axis you don't have to wait for the bound event to set them.

JuanC

[ron.kagan]

Thanx. I now understand that crosstab was indeed overkill.

the problem is there are still issues regarding the axis x as before:

I use (as suggested) this code :

SeriesAttributes se = new SeriesAttributes();

se.ItemsSource = histogramTable.DefaultView;

se.BindingPath = "YValue";

se.BindingPathX = "XValue";

chart1.Series.Clear();

chart1.Series.Add(se);

setting the min/max of the axisx still throw the same exception as before.

[ron.kagan]

Let me add something - when i select from the gallery area/scatter, this works fine - the problem lies in the Bar type chart. i want to show bars with fixed width (the same as the step) so the outcome will look like continous steps :

__

| |__

__| || |

| || || |

[JuanC]

We were able to duplicate the exception and it is in fact related to bar using XY data. Future builds will fix this exception by ignoring the X axis values for the bars. To get a chart similar to what you described you need the following code.

chart1.Gallery = Gallery.Bar;

ChartFX.WPF.Galleries.Bar barAttr = (ChartFX.WPF.Galleries.Bar) chart1.AllSeries.GalleryAttributes;

barAttr.XValues = true;

barAttr.XWidth = 0.2;

Note that the XWidth property is set in the same units as your X axis, also note that overlapping is possible depending on your data.

JuanC

[ron.kagan]

thanx. I already figured the XValues = true and XWidth but what solved this was assigning the XValues = true before giving the series attributes the items source.

I have another open question regarding mouse selection and zooming that was not answered for couple of days so if someone can have a look that will be nice.

[JuanC]

Mouse selection issue should be fixed on build 3833. see original post for details.
