Problem charting NaN

[Karl Mikesell]

Is it possible to not chart values that are Not A Number?  NaN shows in chart as large value, sample attached.

Hello Karl,

I would recommend you to filter those using the dataSource.filter option, for example:  

filter:  { field: "Value", operator: "gt", value: 0 } //show only items with value greater than 0

How to apply the filter to the arrayOfMightBeNumbers, will this then require missingValues: "gap", so no marker appears?

c.kendoChart({
series: [{
...
}, {
type: "line",
markers: {
visable: true,
size: 15,
color: "#ffff33",
type: "triangle"
},
dashType: "dot",
name: "Days",
opacity: 0.0,
axis: "days",
data: arrayOfMightBeNumbers    
}],

Hi Karl,

Applying a filter is done by using a DataSource, which is demonstrated here. The missingValues option works only for null values, so in this case it won't make any difference unless you iterate over the array of data and replace all NaN values with null.
