We have developed a graphing library built for visualizing time series data within our web application, and we're looking for your help to add additional interactive features. Backshift is an open source project, that we're currently using as an alternative to rrdgraph. The existing source code can be found here: [login to view URL] This project consists of adding the following to the Flot renderer: 1) Support for saving the HTML5 canvas as an image: A user should be able to right click on a chart select 'Save image as...' and have a copy of the chart in .png format. The PNG must contain all of the elements that are visible on the chart. There was an existing Flot plugin built for this, [login to view URL], but it does not work properly with our charts. 2) Support for panning and zooming: Users should be able to pan by dragging the chart, or zoom by double clicking and using the mouse wheel. Limits should be set on the panning and zooming so that we always see at least one of the data points. Users should also be able to reset to the original view. Most of this can be achieved with the Navigation plugin ([login to view URL]). 3) Add a table view of the series data: Users should be able to click on a tab called 'Data' on the top right of the graph, that displays a table view of all the series data. The table should be in HTML, and not rendered on the chart's canvas. Users should be able to copy the data, and paste into a spreadsheet. Users should be able to return to the chart by clicking on the 'Graph' tab on the left of the 'Data' tab. This feature should be bundled as a separate Flot plugin. We're looking for functionality similar to [login to view URL], but with the tabs on the top right.

Hi, It seems obvious why right click "save us" doesn't work correctly from this page: [login to view URL] The FLOTR library uses 2 canvas to output the graph, and they have to be combined before a saveing. But it is not easy to make it in one click. It is very interesting task for me. Please, write a feedback. Andrew
