I am using scatter and bar chart for same data with pagination logic. While we loading the second page, previous scatter chart data are not clearing.
For example we have 6 records and showing 4 record per page, first 4 records are displayed properly as shown below
In the second page the 2 records are displayed but previous scatter chart data are not clearing properly as shown below.The issue is i am getting 2 column chart data and four scatter chart data. How can i clear the previous scatter chart data before rendering new page.
Or else please advice, is there any way to add circle indicator to a bar chart like the images show above.
This is a bug that has been fixed recently; the fix should appear in the nightly builds soon. I would also recommend asking questions like that in Sencha forums, there is a greater chance of them being answered there.

I'm wanting to replicate a bar chart done in Power BI using google charts, and one of the features I am attempting to implement is this filter effect as shown by the two pictures I've attached a link to.
Bar Chart Before Filtering
Bar Chart After Filtering
I can add example data in a reply if necessary, but the concept is that the bar chart before shows 100% of data made up of sub categories, and on selecting a category from a drop down menu, the percentage coming from that sub category is highlighted while the rest is made transparent. I've searched through the Google Charts documentation and previous questions however I haven't found any information on how to implement this or if this effect is even possible. The controls included in the API seem to only be able to redraw the chart entirely, not keep the chart and highlight the portion filtered.
I've considered having two charts overlaid on top of each other, with the chart on top changing based on the user category selection and the chart on bottom remaining static, however, I'm not sure if that implementation is optimal or possible. Ideally, I would also be able to replicate this effect on other categorical based charts, such as a pie chart. I'm wondering if anyone has any ideas on a workaround in order to create a similar effect, or some input on whether this effect is even possible using the google charts API and JavaScript/HTML/CSS.
I'm trying to make a highstock chart where the navigator shows summarized data of whats in the main chart. For example, the main chart area will be showing multiple series of a weeks worth of time series data in 5-minute increments while the navigator will have show the whole time series (potentially years long) span in 4 hour increments for each line in the main chart. How should I go about adding these custom series to the navigator?
I am fairly new to JavaScript, let alone charting. I'd appreciate any help in accomplishing the following. I have browsed many JavaScript charting libraries and examples but have not seen any that solve my problem:
I need to create dynamic stacked bar charts as shown in the attached picture. Horizontal axis is time axis. The chart should scroll to left with time along with time-markings on x-axis. Each horizontal stacked bar is for a different item on Y-axis. There will be many items on y axis. Each section of bar will have text as shown. The information about each section and its text is received dynamically.
Thank you!

I have found the Google Charts to be very, very easy to use (https://developers.google.com/chart/?hl=en)
However, in order to have dynamic content, you'll need to have some data source to read from so that you can use something like ajax to constantly ping it for updated data. The Google Charts library will give you a good starting point but it won't be dynamic. You'll have to program that portion but Google Charts is very great in providing you with the basic pie, graph, bar, etc.. 'chart templates' so switching between a bar and a pie chart is super easy.
Currently I am facing issue while rendering chart for large data in EXT JS. Chart gets cut or overlapped.
For example, I have 500 names on x-axis to plot then chart displays only 15 to 20 of them and others get cut. According to my view there should be scroll bar to view whole chart rather cutting the legends. I have tried to found solution for having scroll bars for such large charts but I am not able to find it.
Any other way for viewing whole chart is also accepted.
One workaround I can think about is 'panzoom' interaction.
Please visit link given below to see an official example with 'panzoom'.
http://dev.sencha.com/extjs/5.1.0/examples/kitchensink/?charts=true#line-markers
With 'panzoom', you can zoom in to the chart and then scroll/pan. Zooming in to the chart would make the hidden coordinates visible.
It may look like this because you might have smaller space to render the chart as your data is too big. So you can try with 'pan zoom'. But I don't think so you will get a useful chart. It will still get junked.
I'm outputting a line graph to my page using the Highcharts API and applying the following methods to it:
zoomType: 'x',
event.preventDefault(),
alert(event.xAxis.min) & alert(event.xAxis.max)
This gives the user the ability to highlight a portion of the chart, and have it output the start time and the end time they highlighted without zooming in.
This works great but now I need to literally highlight that section of the graph the user selected. I've been having a look at the xAxis.plotBands method detailed here:
http://api.highcharts.com/highcharts#xAxis.plotBands
xAxis.plotBands allows me to hard code a highlight into the chart but I'm trying to figure out if it's possible to apply plot bands on the fly. It's important that the chart doesn't reset because the user can dynamically add series to the chart as well, so if it resets, the user loses all the series they added. Anyone know if it's possible?
Yes, this can be done with xAxis[i].addPlotBand().
