Display chart in logarithmic way

[stephane]

I would like to display following chart in logarithmic way 

@(Html.Kendo().Chart()
    .Name("chart3")
    .Title("Time Based graph")
         .SeriesDefaults(seriesDefaults => seriesDefaults.Line().Style(ChartLineStyle.Smooth).Markers(false)
          )
           .Series(series =>
           {
               series
                   .Line(new double[] {102, 100, 98, 103, 105, 99, 98, 104, 102, 104, 100, 94, 104, 109, 142, 198, 512, 405, 709, 805, 1203, 845, 1000, 1025, 1002, 1120, 1205, 1508});
           }
           )
           .CategoryAxis(axis => axis
              .Categories(new DateTime[]
              {
                  new DateTime(2011,01,01), new DateTime(2011,01,02), new DateTime(2011,01,03), new DateTime(2011,01,04), new DateTime(2011,01,05), new DateTime(2011,01,06),
                  new DateTime(2011,01,07), new DateTime(2011,01,08), new DateTime(2011,01,09), new DateTime(2011,01,10), new DateTime(2011,01,11),
                  new DateTime(2011,01,12),
                  new DateTime(2011,01,13), new DateTime(2011,01,14), new DateTime(2011,01,15), new DateTime(2011,01,16), new DateTime(2011,01,17), new DateTime(2011,01,18),
                  new DateTime(2011,01,19), new DateTime(2011,01,20), new DateTime(2011,01,21), new DateTime(2011,01,22), new DateTime(2011,01,23),
                  new DateTime(2011,01,24), new DateTime(2011,01,25), new DateTime(2011,01,26), new DateTime(2011,01,27), new DateTime(2011,01,28)
              }
           )
           )

           )

I tries to add that option in VAlueAxis Proporties like that but it changed nothing 

@(Html.Kendo().Chart()
    .Name("chart3")
    .Title("Time Based graph")
         .SeriesDefaults(seriesDefaults => seriesDefaults.Line().Style(ChartLineStyle.Smooth).Markers(false)
          )
           .Series(series =>
           {
               series
                   .Line(new double[] { 102, 100, 98, 103, 105, 99, 98, 104, 102, 104, 100, 94, 104, 109, 142, 198, 512, 405, 709, 805, 1203, 845, 1000, 1025, 1002, 1120, 1205, 1508 });
           }
           )
           .CategoryAxis(axis => axis
              .Categories(new DateTime[]
              {
                  new DateTime(2011,01,01), new DateTime(2011,01,02), new DateTime(2011,01,03), new DateTime(2011,01,04), new DateTime(2011,01,05), new DateTime(2011,01,06),
                  new DateTime(2011,01,07), new DateTime(2011,01,08), new DateTime(2011,01,09), new DateTime(2011,01,10), new DateTime(2011,01,11),
                  new DateTime(2011,01,12),
                  new DateTime(2011,01,13), new DateTime(2011,01,14), new DateTime(2011,01,15), new DateTime(2011,01,16), new DateTime(2011,01,17), new DateTime(2011,01,18),
                  new DateTime(2011,01,19), new DateTime(2011,01,20), new DateTime(2011,01,21), new DateTime(2011,01,22), new DateTime(2011,01,23),
                  new DateTime(2011,01,24), new DateTime(2011,01,25), new DateTime(2011,01,26), new DateTime(2011,01,27), new DateTime(2011,01,28)
              }
           )
           )
           .ValueAxis(a => a.Logarithmic())
)

Could you help me please?

Hello,

The sample code you provided appears to be working in my tests.
Perhaps adding the value axis minor grid lines will help indicate that the axis is logarithmic:
.ValueAxis(a => a.
  Logarithmic()
  .MinorGridLines(minorGridLines => minorGridLines.Visible(true))
  .Max(10000)
)

See attachment for reference.
I hope this helps.
