I'm trying to find if there's a way to obtain information from the "tooltip area" in a Google line chart: https://google-developers.appspot.com/c ... /linechart
There are 2 problems I stumbled upon:
1. In "selection mode", I cannot activate the "tooltip area" on hovering over the charts' points (if I activate it before entering the "selection" mode, the area is no longer visible)
2. In my particular case, the "tooltip area" is also a little bit further than the point, so in browser, when you are taking your mouse from the point in the chart, that area instantly disappears
=> I cannot select the desired "kind".
I can see in the source code of the pages from where I want to extract data the elements that I need (the code is a little bit modified/simplified):
Code: Select all
<script type="text/javascript">google.load("visualization", "1", { packages: ["corechart"] });google.setOnLoadCallback(drawChart);function drawChart() {var data = google.visualization.arrayToDataTable([['x', 'Data1', 'Data2'],['2009',354729,10953],['2010',520073,65617],['2011',501803,53395],['2012',112363,44326]]);var chart = new google.visualization.LineChart(document.getElementById('chart_div'));chart.draw(data, {vAxis: {gridlines:{count: 9},title: 'Title1'},fontSize:10, backgroundColor: 'FFFFFF', chartArea: { left: 75, top: 30, width: 350, height: 200} focusTarget: 'category', title: '', curveType: 'function', width: 600, height: 275});}</script>
A closely resembled line chart you can find in Google Analytics, where the analogous needed data will be the visitor numbers in specific days, extracted from the chart.
Is this doable with Helium Scraper and how?
Thank you very much!
