Hi,

We have to migrate and modernize an old application using new development tools and I try to find the tools which can reproduce the features we had so far.

Having a background image in the chart is one of them.

So my question is, can your Blazor chart component have a background in the chart area only as shown in the attached image?

If yes, is it possible to get the position and the size of the chart area in pixels?

This is because the features in the image must fit to XY scales in the chart, so I need to resize the image accordingly.

I would like to make a Blazor Hybrid application.

Thank you

I recall being told I would have access to source code once I buy a licence.

Now that I have a licence, how do I get access to the source so I can do a local build?

Good day,

I would like to use the Gantt chart for industrial production planning. Independently of the bars, a color highlighting of individual columns (see picture) is to be inserted based on the personnel situation in available employee hours (e.g. workstation 2: 7h/...) and the workload according to the work plan ( workstation 2: .../7h). In addition, a mouse-over on the capacity situation is to be shown per day.

Can this be implemented by the current functions in the Gantt? So far I have not been able to find any configurable elements for the columns.
This is actually enormously important for our project and something like this (or similar) was confirmed in the initiation interview, which among other things prompted the purchase of the license.

Alternatively (even better) would be a dynamic capacity historygram under the Gantt, which is synchronously movable in vertical axe. Here, only a bar (required employee hours per day) would have to be displayed as a total and a constant line (available employee hours) would have to be inserted additionally.
Would a connection with a column chart be feasible from your point of view? (Kind a like: https://demos.telerik.com/blazor-financial-portfolio)


Many thanks in advance.

Is there a way to hide/remove markers from chart, so they also dont appear on hover. When setting visible on ChartSeriesMarker to false, the marker is hidden but will still show up when hovering.

Best Regards,

Hello to all!
I want to share with you my experience of using Telerik charts to build a box and whisker chart.
This chart is extremely useful in statistical data processing to identify outliers in a data set.
https://en.wikipedia.org/wiki/Box_plot

Telerik doesn't have a special box and whisker chart component, but it's pretty easy to make one yourself.
To do this, we need a candlestick chart to visualize the range of data and a line chart to visualize outliers.
The open-source library MathNet.Numerics is used to calculate the summary statistics of five numbers.

Attached is a sample code, enjoy!

Hi all

I've got a question related to chart layout.

In Blazor on the ChartSeries there is a property "Color". Per intellisense a function(point) can be used that will evaluate the series color on point-by-point basis.

But how do you exactly do that ?
Any help is very much appreciated.

FYI
I'm trying this on an Area chart.

Is there a way to change the animation type for ChartSeriesTooltip?

Now it's slides up

Hello,

We need to have string labels in our y-axis

Actually we have an int that matches to an Enum and instead of int number we want to print the Enum string representation

Based on the docs we can either use the Format expression or a Template but none of them allow us for example to use the expression

((MyEnum)value).ToString()

Category labels dont appear on the bottom of the grid?

As far as I understood it, it should pick up the names for the label from @strLCCategory

<ChartCategoryAxis Categories="@strLCCategory">

Which has: "2022-07", "2022-08" in it.

What I am getting:

No labels below that 0 line!

Code below

<GridLayoutItem Column="2" Row="5">
            <TelerikChart Height="400px"
                          Width="700px">
                <ChartTitle Text="Line Counts"></ChartTitle>
                <ChartTooltip Visible="true"></ChartTooltip>
                <ChartLegend Position="ChartLegendPosition.Right"></ChartLegend>

                <ChartSeriesItems>
                    <ChartSeries Type="ChartSeriesType.Line"
                                 Name="@strLCSeries1Field"
                                 Data="@LineCounts"
                                 Width="2"
                                 DashType="@DashType.Solid"
                                 Field="@strLCSeries1Field">
                    </ChartSeries>
                    <ChartSeries Type="ChartSeriesType.Line"
                                 Name="@strLCSeries2Field"
                                 Data="@LineCounts"
                                 Width="2"
                                 DashType="@DashType.Solid"
                                 Field="@strLCSeries2Field">
                    </ChartSeries>
                    <ChartSeries Type="ChartSeriesType.Line"
                                 Name="@strLCSeries3Field"
                                 Data="@LineCounts"
                                 Width="2"                            
                                 DashType="@DashType.Solid"
                                 Field="@strLCSeries3Field">
                    </ChartSeries>
                </ChartSeriesItems>

                <ChartCategoryAxes>
                    <ChartCategoryAxis Categories="@strLCCategory">
                        @*<ChartCategoryAxisLabels>
                            <ChartCategoryAxisLabelsRotation Angle="-45" />
                        </ChartCategoryAxisLabels>*@
                    </ChartCategoryAxis>
                </ChartCategoryAxes>

               @* <ChartValueAxes>
                    <ChartValueAxis AxisCrossingValue="@AxisCrossingValue">
                        <ChartValueAxisLabels></ChartValueAxisLabels>
                    </ChartValueAxis>
                </ChartValueAxes>*@

            </TelerikChart>

        </GridLayoutItem>

private string[]? strLCCategory;
 List<chartLineCountsResult> LineCountsResults = new List<chartLineCountsResult>();
 LineCountsResults = clsDataAccessService.doChartInit("LineCounts", GlobalStuff.msDBEnvir);
 List<string> Categories = new List<string>();
 for (int i = 0; i < LineCountsResults.Count; i++)
            {
                Categories.Add(LineCountsResults[i].Periods.ToString());
            };        
 string[] strLCCategory = Categories.ToArray();

Can't see why the Category labels dont appear on the bottom of the grid?
Should be seeing:
2022-07  2022-08
