hi,
I created a column chart. The X-Axis label (under the Axis) contains all of the columns' headers and under it the row's first column's value.
I don't want all of the columns' headers to appear under X-Axis, since it is redundent for each series and already pretty mapped in the legend.
1. How can I remove it and leave only the row's first column's value for each series?
2. if I add a target line - How can I add a text label to it or add it to the legend?
3. How can I add image to these posts(in the forum)? it asks me for URL, but the image seved locally on my computer...
Thanks

1. If you're creating series with points, you can set the Label property to an empty string on each data point for every series, except the first one. Otherwise, if you want to keep only some of the labels, you have to implement IRenderLabel interface, since there is no way for the chart to know which set of labels you don't want to show.
2. There are multiple ways to add a target line. If you use a composite chart, add a line layer to the CompositeChart.ChartLayers collection and CompositeChart.Legends.ChartLayers collection. The icon and text will automatically appear on the legend. If you use a line annotation or a custom layer, you will have to manually add an icon and text to the legend.
3. In the options tab, click Add/Update, make sure the first radio button is selected and click "Browse" button to upload a local image.
Thanks for your reply.
Can you please show me an example of how to craete series with points? (I'm using column chart bounded to DataTable and I can iterate over the values) - I mean how to populate the series, define the label appearance, etc.
And if you can also show me an example of implementing the interface.
NumericSeries series;foreach (DataRow row in dt.Rows){ series = new NumericSeries(); foreach (DataColumn column in dt.Columns) { series.Points.Add(new NumericDataPoint((int)row[column], column.Caption, false)); } ultraChart1.Series.Add(series);}
