I am setting a label DataFormatString for my line series and I noticed that it is not taking effect. The datasource I am providing to the chart contains a score as a double. I wanted to provide the {0:F} formatter so that I do not display unnecessarily long precision. 

With the following markup:
<LabelsAppearance DataFormatString="{0:F}">
    <TextStyle Bold="true" Color="#003366" />
</LabelsAppearance>

If the data is 56.1, the label is 56

With this markup:
<LabelsAppearance>
    <TextStyle Bold="true" Color="#003366" />
</LabelsAppearance>

If the data is 56.1, the label is 56.1

Is my data format string incorrect, or is it just not working?

Hello,

Indeed, the F format string is not working within RadHtmlChart in the current version of RadControls. This bug has already been logged in our PITS here, so that you can monitor its progress, comment and vote on it.

For the time being you can use the N format string which has the same effect as F format string(e.g. DataFormatString="{0:N2}")
