Hi,

I was wondering if there is a way to use tooltips on a line series instead of a trackball. For example if i clicked on a certain line series in a multiline series chart, the information for that point of the line series would be displayed to the user? 

Thank you.

Hi Erkin,

Thank you for writing.

The following article shows how you can show tooltips: Tooltip | ChartView. When using line series, you will need to make the data points a bit bigger show the user can easily hover them: 

I hope this will be useful. Let me know if you have additional questions.

Dimitar,

 

Thank you very much for that information that helped out a lot. I do have another question that maybe you can answer.

I want to use the tooltip as a custom tooltip that displays some more information about the current point the user is pointing at. 

currently I have the example code given in the tooltips api for custom tool tips.

 

This is the current controller method I am using. 

 

        private void tooltipController_DataPointTooltipTextNeeded(object sender, DataPointTooltipTextNeededEventArgs e)
        {
            e.Text = "Voltage:\nCurrent:\nTemperature:";
        }

 

Basically I want to take the data from that current point that is showing the tooltip (X,Y info etc.) and display it for the user.

Any ideas?

 

Thank you.

Hi Erkin,

You just need to cast the point to the appropriate type. For example:
