Was the 2nd-Y axis patch (No. 13832;
http://bugs.freepascal.org/view.php?id=13832) ever incorporated into the
Lazarus/TAChart release? I'm new to Lazarus and don't quite know how to
interpret the bugtracker page. I do know that I cannot find some of the
changes mentioned in the patches -- such as for TAGraph -- in the latest
version of TAGraph.
I do scientific programming and am trying to update some of my older
Delphi/Pascal programs. I need the ability to independently set YMax
and YMin values for both Y axes on climate diagrams (which plot both
monthly precipitation and temperature data) on the same chart.
Precipitation data are plotted as bar graphs, temperature data are
plotted by line series. I can get all the data series plotted, but I
cannot get the precip and temp data scaled properly.
In the older version of my program (which used Delphi/Teechart), I had
the precipitation axes set from 0 to 30 cm and the temperature axes set
from -90 to 60 degrees centigrade.
If this list accepts attachments, I can forward a wmf with an actual
chart. Here's the current version of the plotting procedure:
procedure TCLIMatePLOTForm.CLIMPLOTButtonClick(Sender: TObject);
var
Mnth: integer;
begin
ClimateDataChart.Title.Text.Clear;
Series_mpr.Clear;
LineSeries_mt.Clear;
LineSeries_mxt.Clear;
LineSeries_mnt.Clear;
with ClimateDataChart.Title.Text do
Add(SiteName);
if lat < 0 then begin
with LineSeries_mt do begin
for Mnth := 7 to 12 do
Add(mt[Mnth], AbMonth[Mnth], clPurple);
for Mnth := 1 to 6 do
Add(mt[Mnth], AbMonth[Mnth], clPurple);
end;
with LineSeries_mxt do begin
for Mnth := 7 to 12 do
Add(mxt[Mnth], AbMonth[Mnth], clRed);
for Mnth := 1 to 6 do
Add(mxt[Mnth], AbMonth[Mnth], clRed);
end;
with LineSeries_mnt do begin
for Mnth := 7 to 12 do
Add(mnt[Mnth], AbMonth[Mnth], clBlue);
for Mnth := 1 to 6 do
Add(mnt[Mnth], AbMonth[Mnth], clBlue);
end;
with Series_mpr do begin
for Mnth := 7 to 12 do
if PrecipData <> 1 then
Add((mpr[Mnth]/10), AbMonth[Mnth], clAqua)
else
Add(0, AbMonth[Mnth], clAqua);
for Mnth := 1 to 6 do
if PrecipData <> 1 then
Add((mpr[Mnth]/10), AbMonth[Mnth], clAqua)
else
Add(0, AbMonth[Mnth], clAqua);
end;
end else begin
with LineSeries_mt do
for Mnth := 1 to 12 do
Add(mt[Mnth], AbMonth[Mnth], clPurple);
with LineSeries_mxt do
for Mnth := 1 to 12 do
Add(mxt[Mnth], AbMonth[Mnth], clRed);
with LineSeries_mnt do
for Mnth := 1 to 12 do
Add(mnt[Mnth], AbMonth[Mnth], clBlue);
with Series_mpr do
for Mnth := 1 to 12 do
if PrecipData <> 1 then
Add((mpr[Mnth]/10), AbMonth[Mnth], clAqua)
else
Add(0, AbMonth[Mnth], clAqua);
end;
end;
