Hi Danail,

I've tried the one you suggest as well as using the _chartObject bypassing the get kendo object stage (as seen in that link). Neither method works for me.

Full js being used is shown below. Hope you have a suggestion !

function pageLoad() {

if ($find("uxRadHtmlChart") !== null) {

//try {

var kendoWidget = $find("<%=uxRadHtmlChart.ClientID%>").get_kendoWidget();

kendoWidget.options.series[0].color = function (e) {

if (e.value < e.dataItem.RedValue) {

return "red";

} else {

if (e.value >= e.dataItem.GreenValue) {

return "green";

} else {

return "orange";

}

kendoWidget.redraw();

//} catch (err) {

// // do nothing

//}

var chart = $find("<%=uxRadHtmlChart.ClientID%>");

chart._chartObject.options.yAxis.majorGridLines.step = 5;

chart.repaint();

}

WindowResize();

};

Hi Danail

I've created a stand alone project for this and the issue still appears. Code is pasted below.

The version of the Web.UI being used is 2015.1.401.45

Fingers crossed you can duplicate the issue.

Jon

Hello Jon,

Thank you for providing us a runnable sample that reproduces the issue.

You can use valueAxis for category series like Column series and yAxis for numeric series like bubble and scatter, in order to access the y-axis. For example:

<script type="text/javascript">

function pageLoad() {

var chart = $find("uxRadHtmlChart");

chart.get_kendoWidget().options.valueAxis.minorGridLines.step = 2;

chart.get_kendoWidget().options.valueAxis.majorGridLines.step = 2;

chart.repaint();

};

</script>

Hi Jon,

If you want to change the step of the y-axis you can use the YAxis.Step property. If you want to change the step through which major/grid lines render you should use the code I have provided in my previous post, which works properly on my side. Note that if you set a higher value for the grid lines step it is normal for them to no appear because there may not be such slots.

You can make a test with the code below, where is illustrated how to set the step of the yaxis and major/minor grid lines. For your convenience I have also created a snapshot with short description to get a better understanding - http://screencast.com/t/qOavfgziio
