ananthkumar.ks Report post Posted November 18, 2013 Hi team, We are currently looking for a chart which will work like google finance.Chart which loads data on-demand and gets appended to the existing data that is rendered already may be.For example, I have a chart with data 250 to 300 with X-axis split equally on 5 unit intervals. If i drag the chart internally , there should be an ajax request to get the data , say from 220 to 250 and change the scale according and prepend to the existing dataset. If i scroll again from 220 to 260, data should be rendered from dataset existing(till 300). Share this post Link to post Share on other sites
Haritha Report post Posted November 19, 2013 Hi Ananth, Welcome to FusionCharts Forum If you want the chart to get updated when the data is present/modified (can check this is your code by coordinating with your database) then you may use Real-time charts. Real-time charts update their data in certain intervals and the new data on the chart is made to get appended to the existing data on the chart. Please have a look at :http://www.fusioncharts.com/demos/gallery/real-time-charts/chart.asp?id=realtime_1 For your requirement of chart having macroscopic view (250 to 300) and showing microscopic view of data on selection of particular data ( 220 to 250) and scaling of x-axis according to the change, then you may use Zoom Line chart. Try selecting and dragging a particular area on the chart from : http://www.fusioncharts.com/demos/gallery/zoom-line/chart.asp?id=zoomline_3 Hope this helps.

ananthkumar.ks Report post Posted November 21, 2013 Hi,My question was different. I asked for a chart which does not request data automatically but on user interaction. Zoom line charts require all data to be presented at one shot and it doesnt give me the feature i requested. My request is different. I wanted a chart where i get only a data for today. If drag the chart internally to yesterday, i should get the data by an ajax request and prepend to the existing data. If you have a look at google finance, you will get a better idea. Now, can you let me know a chart that can provide me this? Share this post Link to post Share on other sites

Haritha Report post Posted November 25, 2013 Hi, It is not possible to plot the chart of a given day first and then obtain the data and plot the data of chart to yesterday when the user drags the chart, as of now. Hope this helps. Share this post Link to post Share on other sites
