I was using PHPGraphLib for my php version 7.0 and it was working absolutely fine. However, I have switched my local server from 7.0 to 7.1 and now it has started giving me an error saying..
A non-numeric value encountered
at /my_website_path/phpgraphlib.php line 987
Hence I went to this particular line and found this code at line number 987.
$raw_size = $high_x - $low_x +1;
And changes this chunk of code to this (Ref https://github.com/elliottb/phpgraphlib/issues/30#issuecomment-394975371 ).
raw_size = $data[$high_x] - $data[$low_x] +1;
And I have successfully surpassed this error. But now I am getting another error saying..
A non-numeric value encountered
at /my_website_path/phpgraphlib.php line 381
I went here and found this code.
$xStart = $this->y_axis_x1 + ($this->space_width / 2) + ((key($data_set) - $this->lowest_x) * ($this->bar_width + $this->space_width));
And tried to replace with this code.
$xStart = (float) $this->y_axis_x1 + ((float) $this->space_width / 2) + ( (float) (key( $data_set) - (float) $this->lowest_x) * ((float) $this->bar_width + (float) $this->space_width));
Yes I am unable to make it work in my php version 7.1
I have tried to find ways and researched but yet to find which works for me.
I have also tried to search this library which is working for 7.1 but it seems like they have not upgraded to php 7.1 yet.
Can someone guide me how can I overcome these issues and make it somehow work for my latest php version.
