Will,
In the screenshot we can see that some other fonts (outside the chart) are also blurred – text saying “Please select”. Hence am not sure if the issue related to CanvasJS library itself. Please answer below questions so that we can further investigate the problem.
- In which version of IE did you take the screenshot?
- Are you emulating IE8 rendering via IE11/IE10??
- Can you check if the page has been “Zoomed” in IE?? If yes, please reset the IE zoom level and try again.
