Use Fixed Bar Size
You might need to set the size of the default drawing element of the bars to the same size.
The following example demonstrates how to use the series.visual function to scale the default drawing element of the bars and achieve this behavior.
<div id="chart"></div>
<script>
var BAR_SIZE = 10;
$("#chart").kendoChart({
series: [{
type: "bar",
data: [1, 2],
visual: function(e) {
//create the default visual
var visual = e.createVisual();
//scale it so that it has the predefined size
visual.transform(kendo.geometry.transform().scale(1, BAR_SIZE / e.rect.size.height, e.rect.center() ));
return visual;
}
}]
});
</script>
</div>
