How to display HRULE lines in preview graphs

[fdessart]

Hello,

I have a few graphs, with AREA, LINE1 and HRULE displayed.
However on the preview graphs, only AREA and LINE1 are displayed, not the HRULE line!

Is there a way to change this?

Thanks for your help.

I can't tell you what my thinking was at the time, but for some reason what you are describing is coded as such. You can try to disable it by commenting out the following lines of 'include/rrd_functions.php':

873, 874, 875, and 877

I did not test it, but I do not see why it would not work.

I commented out the following lines:

case 'HRULE':
$text_format[$i] = ereg_replace (":", "\:" ,$text_format[$i]); /* escape colons */

// if ($graph_data_array["graph_nolegend"] == true) {
// $value_format[$i] = "0";
// }else{
$value_format[$i] = ereg_replace (":", "\:" ,$value_format[$i]); /* escape colons */
// }

$graph_items .= mysql_result($sql_id_item, $i, "tname") . ":" .
$value_format[$i] . "#" . mysql_result($sql_id_item, $i, "hex") . ":\"" .
"$text_format[$i]$hardreturn[$i]\" ";
break;


But now the graph is not displayed at all and I get the following error in Apache error_log: "ERROR: can't parse '#F51D30:'" where #F51D30 is the color of my HRULE line...

Any idea?

Thanks.

I decided to test this on an installation of cacti. It works fine for me in both preview mode and non-preview mode. Here is an example:

Make sure you enter values for VRULE in the 'Value' field in the format 'HH:MM'. In this case I entered 0:00 and the graph renders fine in all cases.

Perhaps something else is up.

I talked about HRULE, not VRULE.

Hi!

I modified line 876 in include/rrd_functions.php from
$value_format[$i] = "0";
to
$value_format[$i] = mysql_result($sql_id_item, $i, "value") ;
and it seems to work fine for me.

Maybe this is not the best solution.
