Sorry for yet another question.
How can I customise the tooltip on UltraDataChart? It seems to pick up strange defaults. For example, it uses the header from the series in the datasource, rather than using the Title from the series. It also displays a full datetime when I only have dates, and finally it displays the numeric value without any formatting even though the y-axis is formatted in a particular way. So whilst I love the layout and colour of the tooltip, the formatting really needs to be fixed:
Also, is there a way to prevent the lines from being blurry? It seems to attempt to anti-alias to get to sub-pixel accuracy, but it just makes the graph look messy, because some lines are thicker than others:
In order to understand the scenario I setup a StepLineSeries datachart sample and set up a default tooltip .And I find title is displayed in the tooltip with no issue. And about displaying the full datatime ,you can use xAxis.label property or xAxis. FormatLabel event to format it.
I attached my sample here which I used to test it.If the project does show the product feature working correctly, this indicates a possible problem in the code of your application. It will help if you can provide a small, isolated sample application that demonstrates the behavior you are seeing.
Or, if this sample project is not an accurate demonstration of what you're trying to do, please feel free to modify it and send it back, or send a small sample project of your own if you have one.
Also about anti-alias ,i did little research and fine we do not have any control over ,we dont have any API to control it.
Please let me know if I can provide any further assistance.
