Stacked bar chart with line chart

Hi all,

I want to create stacked bar chart with line chart. My requirement as below,

1. This chart will use a stacked bar chart and left Y-axis represent numeric values with no specific interval. 
    Right Y-axis represent percentage and both Y-axises max set based on the value.
2. X-axis represent the date for each of the past 365 days, including today, with the oldest date on the left and the newest date on the right. (Interval should use monthly)
3. This chart also will include a line chart to represent two dashed-lines align with above mapped axises. (Note: One line should be represent the percentage right Y-axis and other one will represent left Y-axis with normal numeric value and both lines will use shared X-axis)
4. This chart will include a legend to the left side of the chart and displaying the color and data name of each of the represented data. 
(Note: The maximum number of supported data is 10 without two lines of chart (All 12 legends) and legend name can be displayed 20 characters with horizontal scroll bar)

Data format

function getChartData(): Object[] {

let chartData: Object[] = [{
'date': new Date(704692800000),
'stackedData1': 2.5,
'stackedData2': 3.0,
'stackedData3': 1.0,
'stackedData4': null,
'stackedData5': null,
'stackedData6': null,
'stackedData7': null,
'stackedData8': 3.5,
'stackedData9': null,
'stackedData10': 2.5,
'lineData1': 1.2,
'lineData2': 25, // Percentage value
},
{
'date': new Date(1273185387),
'stackedData1': null,
'stackedData2': null,
'stackedData3': 1.5,
'stackedData4': 2.5,
'stackedData5': 1.0,
'stackedData6': null,
'stackedData7': null,
'stackedData8': 4.0,
'stackedData9': 1.0,
'stackedData10': null,
'lineData1': 1.8,
'lineData2': 50, // Percentage value
}
// Other rows here
];
return chartData;
}

Please be kind enough to give me a stackblitz example for my convenience.

Thank you...

Hi Neo, 
 
Greetings from Syncfusion. 
 
We have analyzed your queries. We have prepared a sample with your data based on your all queries. Also we would like to let you know that, In EJ2 we have used legend paging instead of legend scrollbar support. Please find below sample and screenshot,

Hi,

It's working perfectly. I have few things to do further. My requirement as below,

* I want to enable drill-down in the chart. The chart X-axis should be separated into two sections which are divided from the 365 days. These two sections are clickable.
   Left section contains 182 days and right section contains 183 days. If either side is clicked then the display will be redrawn the chart in full screened dialog modal with      the new time period being set by the duration of the section being selected. In the next level that selected section (Assume left 182 section) can be clickable which separated into 6 section indicating monthly. Lastly, if user selected one of sections 6 that duration of the section should be represent in the chart.

Original chart - [182  Days][183 Days]
New chart in the Dialog - [30 Days][30 Days][31 Days][31 Days][30 Days][30 Days] - Section 1, 
                                          [30 Days][30 Days][31 Days][31 Days][31 Days][30 Days] - Section 2
Same chart in the Dialog - [30 Days] - Some selected month

Note: - X-axis represent the date for past 365 days, including today, with the oldest date on the left and the newest date on the right.
          - Open dialog modal for first level only. Other levels should be show in the same chart.


Highly appreciate your support.
Thank you.

Hi Isanka, 

We have analyzed your query. We have prepared a sample for your requirements. While clicking on the chart, based on the range in x axis, another chart with required range will be opened in dialog.  Again clicking on the chart which is rendered in dialog, it re rendered in the same chart.  

Sample link:  
We have prepared the stackblitz sample link.  

And also please refer the sample link for single level drill down on point on the chart. 

Kindly revert us if this sample, doesn’t meet your requirement.  

Regards, 
Kesavan
