My Magento having over 1 lakh products orders, but graph not showing according to sale on magento admin dashboard. please help me what i need to do. Graph showing blank. no graph image is showing. Thanks in advance
Taken from this site
Allow access to this URL on your firewall: http://chart.apis.google.com/chart
Make sure Magento does not try to fetch the image through PHP Locate this file: app/design/adminhtml/default/default/template/dashboard/graph.phtml And change: "getChartUrl()" to "getChartUrl(true)"
This will cause Magento to just return the image location at http://chart.apis.google.com/chart instead of downloading it through PHP.
Both solutions seem to work great. But Solution 2 could throw a warning if you are running your Magento back-end on an SSL connection (which should be doing by the way!)
After implementing this solution the Magento charts or graphs are shown and you can again admire your sales figures!
In case you've been googling this in 2019 - this is an issue with deprecated Google Image Chart API. There is a Magento 1 module that fixes missing charts - https://github.com/onilab/magento-1-google-api-chart-fix
If the problem is just related to 24 Hours Chart it can be cased by minimal allowed GET variable length settings of suhosin as Titan Lee described on his blog:
This is related to the minimal allowed GET variable length settings. Check your settings for suhosin:
Add/Edit line - > suhosin.get.max_value_length = 1024
If the above file doesn't exist for you. Then locate & edit,
