| Sir, I am have problem while zooming the graph......the graph keeps on zooming even after last data points... There are 2 scenario: Scenario 1: I am getting day data from 9 to 5pm...... sometimes it happens say full data is not received............. so i have 2 points from 9 to 10am,2 points from 10 to 11am,etc...... so if i have only say 50 points from 9 to 5 pm...then there comes problem while zoomin.... means if there are few points and more time scale from 9am to 5 pm then graphs keeps on zooming.... here is the code.... minduration = 60// 60seconds firstpoint = m_timestamps[0]; maxduration = m_timestamps[noofpoints -1] - firstpoint; chartviewer.setzoominwidthlimit(minduration / maxduration); This code doesn't works.......... please help me out............... Scenario2: if i am having complete day data from 9 to 5pm then this code works minduration = 60// 60seconds firstpoint = m_timestamps[0]; maxduration = m_timestamps[noofpoints -1] - firstpoint; chartviewer.setzoominwidthlimit(minduration / maxduration); now i am having to edit control fields say starttime and endtime.... if i set starttime as 9 and endtinme as 5pm then there is no problem while zooming....zooming stop after sometime.................... but if i set starttime as 9 and endtinme as 3pm on same data and then if i try to zoom at the end of the graph the graph disappears and zooming continues.......... please help me out of this zooming and scrolling problems................ In both cases i want to stop zooming to a particular limit say last 5 points....etc how do i achieve this.its urgent........ | |
