Good morning. I'm using json to render a live-update HLED chart. I have it all working well until the data value returned from the database happens to fall above (or below, as in -1 error state) the upperlimit set for the HLED widget. I would hope/expect that it would fill the HLED since, in this case, 18 > 12. However it draws the HLED with a zero value. In the case in question, the $led_end=12 and the data returned by the datastreamURL query is 18. Is there a way to have this behave as I would expect, where "since 18 > 12, assume 12 and fill chart"? Know what I mean? =) Here's a piece of the perl script I use to generate the JSON in question: ($name, $itemid, $label, $x, $y, $qtype, $units, $led_start, $led_warnlow, $led_warnhigh, $led_end, $environ) = split(/,/, $line); $chart = { manageresize => "1", origH => "120", origW => "310", basefont => "Cabin", basefontsize => 10, lowerlimit => "$led_start", upperlimit => "$led_end", showLimits => "1", bgcolor => "000000", bgalpha => "88", numbersuffix => "$units", majortmcolor => "646F8F", majortmheight => "9", majortmthickness => "1", majortmnumber => "6", minortmcolor => "646F8F", minortmheight => "3", minortmnumber => "3", tickvaluestep => "1", ticksbelowgauge => "0", decimalprecision => "1", forcedecimals => "0", palettethemecolor => "FFFFFF", charttopmargin => "30", chartbottommargin => "10", ledborderthickness => "1", ledgap => "2", ledsize => "3", decimals => "1", refreshInstantly => "1", clickURL => "j-renderChart-$name", dataStreamURL => "/perl/ops/garch-$release_env/getdata.pl?name=$name", refreshInterval => "20" }; $initial_value = { value => "$default_value"}; $annotation_items[0] = { color => "FFFFFF", type => "text", bold => "1", font => "Cabin", fontSize => "11", x => '$chartCenterX', y => '$chartStartY+15', label => "$label ($environ)" }; $groups[0] = { id => "Group1", items => \@annotation_items }; $annotation = { groups => \@groups }; $color[0] = { minvalue => "$led_start", maxvalue => "$led_warnlow", code => "00FF00" }; $color[1] = { minvalue => "$led_warnlow", maxvalue => "$led_warnhigh", code => "FFFF00" }; $color[2] = { minvalue => "$led_warnhigh", maxvalue => "$led_end", code => "FF0000" }; $colorrange = { color => \@color }; $list = { chart => $chart, value => $initial_value, annotations => $annotation, colorrange => $colorrange }; $json_text = encode_json $list; print header('application/json'); print $json_text;
