I am using Donut chart for displaying data categorized into two categories. Whenever dataseries is updated, sometimes Highcharts does not render the series data in provided order.
And because of this, data is not displayed as per category.
Expected Chart:
Current Behavior:
Series Options Provided :
I am trying to create side by side bar chart with the line chart on the same axis. My X-axis shows months of the year with the new cases and completed cases as bar charts and I need to overlay it with the Turn around Time as a line chart.
Bar Chart
The data provided has different case status (New, Open & Resolved) and the starting date for the cases. I need to create calculated fields to count the number of new and completed cases and display it in the side by side bar chart. I am connected to a live data source. So, I think pivot is not an option for me as it is not getting displayed when I do a right click on Tableau.
Tableau is unable to natively build a side-by-side with lines due to how side-by-side charts are built - each cohort holds the cluster of bar charts, so the lines will only be continuous within a cluster.
That said, this can be done easy enough. Take a look at chart 37 and its accompanying video demonstrating how to build this from my how to page: Datawonders | Show Me
The workbook is downloadable too

I wanna show several series in one chart, and I only wanna the first series to be shown by default. The other series's data shouldn't be fetched until the according legend is clicked, so that the loading speed will be faster.
Only when the according Legend is clicked, then the chart will use AJAX to fetch data and show it, Can highcharts do that?
I have seen several similar questions about lazyload, but they are all using highstock, can highcharts.js do it?
I was trying candlestick chart using highchart ( highstock ) and find out that when I increase/decrease Navigator in candlestick chart the width of candlestick get changed. Sometime it display high, open, close and low for one hour interval whereas sometime it is displaying for month. I would like to grab these dynamically changed candlestick width ( not the pixel width but the real time interval) and display them in the chart title. Is there anyway I can get these information and update them dynamically in chart subtitle?

Thank You
What you are seeing are the effects of plotOptions.series.dataGrouping (API Reference) where the data is grouped and values are approximated to display the data faster. If you look at the example for units on the above linked page you'll find that you can determine and set what those groupings are. The grouping isn't truly dynamic, it's predefined.
I have a column chart about 2000 columns. It renders very slowly. I get data from Struts and push it directly into chart. I tried to disable animation and use xAxis.labels.step option but it's still slow. How to speed up the chart?
