The axis is numerical, but it could have a DataLabelsField property like the x-axis so text for each label is taken from the datasource (a label per datasource row). Then the numerical values (YValue) of each item can be rounded to the nearest integer and if that matches an axis item's index the series item will correspond to this axis item.
Hi, You can use templates for the y-axis in order to display text instead of the values. Such an example is illustrated in this demo - http://demos.telerik.com/aspnet-ajax/htmlchart/examples/functionality/clienttemplates/defaultcs.aspx
We would like to switch from another product to the telerik charts but can't because hints or categories at the y-axis are absolutely important to our customers. ANY solution to add some text to the y-axis labels would be fine. We wonder noone else is missing this feature.
