Hi,

 

I am using a stockchart graph.  I understood how the granularity of the category axis is working and I set it to "Fit" in order to have a displayable amount of dates, regardless of the ‚Äčtimespan of my data (which is variable).  However, the side effect of this is that not all values of my graph are displayed, but only those at the date steps that are computed by the graph based on my display width and time span.

How can I keep the category axis working as it does, but have all values displayed on the graph. 

I have customized the tooltip to display the value and the precise date/time, so you will get the date/time info in this way even if not displayed on the category axis.

 

Thanks for your help.

Olivier

In attachment, a screenshot illustrating the current situation.  Here is the corresponding code:

 

Html.Kendo().StockChart<FundGraphSample.Models.VNIHistory>()
        .Name("VNIHistory")
        .ChartArea(chartArea => chartArea.Background("#fafafa"))
        .DataSource(ds => ds.Read(read => read
            .Action("_VNIJsonData", "VNIData")
        ))
        .DateField("Date")
        .CategoryAxis(axis => axis
            .Name("displayedCategories")
            .Date()
            .BaseUnit(ChartAxisBaseUnit.Fit)
            .Crosshair(hair => hair
                .Width(2)
                .Color("black")
            )
            .MajorTicks(tick => tick
                .Visible(true)
                .Size(10)
            )
            .Labels(labels => labels
                .DateFormats(formats => formats
                    .Days("dd/MM/yyyy")
                    .Months("MMM 'yy")
                    .Weeks("dd/MM/yyyy")                    
                )
                .Rotation("auto")
                .Font("normal 16px HelveticaNeueLT-Thin, \"Courier New\"")
                
            )
        )
        .Series(series => {
            series
                .Line(s => s.Value)
                .Color("#c5281c")
                .Markers(false)
                .Width(3);
        })
        .ValueAxis(axis => axis
            .Numeric()
            .Line(line => line
                .Width(0)
            )
            .Labels(labels => labels
                .Font("normal 16px HelveticaNeueLT-Thin, \"Courier New\"")
                
            )
        )
        .Tooltip(tooltip => tooltip
            .Template("#= kendo.format('{0:C3}', value)#<br/>#= kendo.format('{0:dd MMM yy}', category)#")
        )
        .Navigator(nav => nav
            .CategoryAxis(axis => axis
                .Date()
                .BaseUnit(ChartAxisBaseUnit.Days)
                .AutoBaseUnitSteps(step => step
                    .Days(1,7)
                )
                .Labels(labels => labels
                    .DateFormats(formats => formats
                        .Days("MMM yyyy"))
                    .Rotation("auto")
                    .Font("normal 16px HelveticaNeueLT-Thin, \"Courier New\"")
                
                )
            )
            .Series(series => {
                series.Line(s => s.Value).Color("#c5281c").Markers(false).Width(1);
            })
            .Select(
                DateTime.Parse("2014/10/16"),
                DateTime.Parse("2015/10/15")
            )
        )‚Äč

Hi Olivier,

I am afraid what you are trying to achieve is not supported - by design the data for a particular date period is aggregated and this behavior cannot be prevented. Please excuse us for any inconvenience this may cause.
