I am using data from a local database. I have created credentials to allow your access to my joomla setup, but I dont know how to provide them to you, since I cannot find a section visible only to administrators in this forum tool, the available Hidden text section will only hide it from guest users. Perhaps you could provide me your email ?

The main issue is that I would like to hide null values from the chart. I have three data series in this specific line chart, but for two series the majority of values are null, they are actually set to null in my database, not 0, but then when data is loaded in the chart these null values are converted to 0. An example of this chart can be found at www.intratec.us/new_website/test .

Thank you in advance for the support.

Hello Luiz,
Can you please let us know which data format are you using to generate the charts e.g. Dynamic CSV, Manual Input, Database? Can you please also send us your back end & FTP login credentials via Contact us form so that we can also have a look on your chart settings?


Thanks
Daniel

I have found the solution for this problem, there is a dropdown to define what kind of data is the values on the horizontal axis, I chose string, and it worked fine.

I have a new problem though, I need to be able to hide null values from the Line chart, I read online that it is possible to be done with the google API setting the interpolateNulls option to false, but I dont know how to set this option in the vChart extension.

Hello, I am having problems with Line Charts.

I need to show a line chart in which the horizontal axis displays the months of one year (jan, feb, ...) and the vertical axis have an integer value for each month.

When I try to use char values in the horizontal axis, the chart does not load, is this the usual behavior ?

Then I tried using a sequence of integer values representing the months of an year and it worked, but I would like to show a text label in the horizontal axis instead of its value integer, is this possible ? I have looked everywhere and I couldn't find a way to do it.

I know that it is possible to be done with the google chart api, because you can set a label for every value, and it would show the label instead of the value in the horizontal axis. I have looked for this option in the vChart but I don't know where to find it.
