Hi, I have an issue that I cannot resolve. I followed the process on that blog but for some reason, the X Axis label will only change if i hover on the scatter plot. Also, the X axis label changes according to the data of the hovered plot.

This is the code that i used. I also used the data that u post above this email chain. Thanks.

NLDChart.Axis.X.Labels.ItemFormat = AxisItemLabelFormat.Custom

"<DATA_VALUE:#>"

Regards,

Bobby Pohan

This part makes me think that you are talking about tooltips and not the x axis labels.  Are you saying the axis labels toggle back and forth depending on whether you are above the data point.

The labels are dependant on the data.  If this is a scatter chart then the x and y axis will both be numeric.  By default, our axis will dynamically change the range based on the range of data.  If you want it to be static, you have to look at the "Custom Axis Range" section of the blog post.

If this doesn't answer you question.  Could you be specific on what you are trying to do?

Thanks for the quick response. What I want to do is to be able to change the X Axis label by lets just say, clicking a button. So, if this is the data that i use:

dt.Columns.Add("Month", typeof(string));

dt.Columns.Add("Leads", typeof(int));

dt.Columns.Add("Sales", typeof(int));

dt.Rows.Add("January", 120, 50);

dt.Rows.Add("February", 90, 44);

dt.Rows.Add("March", 70, 22);

dt.Rows.Add("April", 66, 21);

dt.Rows.Add("May", 80, 42);

dt.Rows.Add("June", 85, 48);

by default, i want to show the X axis label as the second column (i.e. 120, 90, 70, etc.). Then, by clicking the button, I want to change the X axis label to

January, February, etc. from the 1st column in my scatter plot graph. Is this possible? Like i said previously,

I used :

NLDChart.Axis.X.Labels.ItemFormat = AxisItemLabelFormat.Custom

NLDChart.Axis.X.Labels.ItemFormatString =

"<SERIES_LABEL:#>"

But, the label on the X axis' ticks changes based on what data plot that I hover. Again, I appreciate your help.

You want to toggle between

ultraChart1.Axis.X.Labels.ItemFormat = Infragistics.UltraChart.Shared.Styles.AxisItemLabelFormat.DataValue;

ultraChart1.Axis.X.Labels.ItemFormat = Infragistics.UltraChart.Shared.Styles.AxisItemLabelFormat.ItemLabel;

Thanks, I tested, it worked by showing the correct X axis label. But, when I click the button to run the

ultraChart1.Axis.X.Labels.ItemFormat = Infragistics.UltraChart.Shared.Styles.AxisItemLabelFormat.ItemLabel;

I received the attach result. The X axis are only ITEM_LABEL. Any suggestion?

For a scatter chart both the x and y axis is numeric.  There is no item or series equivalent at each of the tickmarks. 

If you wanted to use a scatter, instead of line or the other chart types, then you could set a custom range on the axis and use a custom token using IRenderLabel.  This allow you to post any string that you want.  So, like 1 to 12.  Then convert those to months.  You can find IRenderLabel implementations all throughout the forum including my blog post.

I tried the attachment that you included on ur previous post. It worked untl I changed the graph to scatter plot. So, I assume this only works on bar graph then? Is there a way to work around so that I can use the same functionality in the scatter plot? Thanks. Bobby Pohan

Hi Sung Kim,

I am not sure what is happening over here. I even tested your code on the Infragistics sample code. I used LabelsTitlesTooltips: CustomToolTips form. I changed the graph to scatter plot. I still received the same behavior. It "<ITEM_LABELS> on the X axis. Let me remind you that I use VB.Net instead of C# if that makes any difference. Do I need to set up something when changing the graph to scatter plot? Thanks. Bobby Pohan

I am using the following and not seeing an issue (9.1 vs08 sample attached):

private void Form1_Load(object sender, EventArgs e)
{
    DataTable dt = new DataTable();
    dt.Columns.Add("Month", typeof(string));
    dt.Columns.Add("Leads", typeof(int));
    dt.Columns.Add("Sales", typeof(int));
    dt.Rows.Add("January", 120, 50);
    dt.Rows.Add("February", 90, 44);
    dt.Rows.Add("March", 70, 22);
    dt.Rows.Add("April", 66, 21);
    dt.Rows.Add("May", 80, 42);
    dt.Rows.Add("June", 85, 48);
    ultraChart1.Data.DataSource = dt;
    ultraChart1.Data.DataBind();
}

private void button1_Click(object sender, EventArgs e)
{
    ultraChart1.Axis.X.Labels.ItemFormat = Infragistics.UltraChart.Shared.Styles.AxisItemLabelFormat.DataValue;
}

private void button2_Click(object sender, EventArgs e)
{
    ultraChart1.Axis.X.Labels.ItemFormat = Infragistics.UltraChart.Shared.Styles.AxisItemLabelFormat.ItemLabel;
}
