Limiting number of x labels on chart when the x axis is string type

[JustinOberle1]

For Thingworx 10.0.0 in the line chart widget...

I am trying to limit the number of x axis labels. I see this is possible if the x axis type is numeric or date type. However, with string type, the property numberOfXAxisLabels is not visible. Is there a way to limit this somewhere when the x axis is a string type?

Hi @JustinOberle1 

In ThingWorx 10.0, limiting the number of x-axis labels in a line chart widget is straightforward for numeric or date types, as the property numberOfXAxisLabels is available.   But as you found, when using a string type for the x-axis, this property is not visible, and there is no direct option to limit the number of labels.

To manage the display of x-axis labels when using string types, consider the following approaches:

Data Preprocessing: Before binding your data to the chart, preprocess the data to limit the number of string labels. You can create a new data set that only includes the desired labels.

Custom Widget: If you have development capabilities, you could create a custom widget that allows for more control over the x-axis label rendering, including limiting the number of labels displayed.

Styling Adjustments: Adjust the styling or layout of the chart to accommodate more labels without overcrowding, such as rotating labels or using a smaller font size.

If you need assistance to develop a solution, such as in the case of a custom widget, please contact your Sales rep or reach out to the Sales team.

Regards.

Thanks for the reply. This is what my initial research found as well. Option one wont work in our case and option 2 is undesirable for a few reasons. Option 3 might be the only option for now, although it is not going to look great. Thanks for confirming this!
