search keys can't work in SObjectChartWdg

[EricTsuei]

I am creating a custom Layout using SObjectChartWdg. 
using tactic 4.5

code is:
<element>
  <display class="tactic.ui.chart.SObjectChartWdg">
    <search_type>production_management/main_page</search_type>
    <title>test budget</title>
    <x_axis>name</x_axis>
    <elements>budget</elements>
    <search_keys>"production_management/main_page?project=test"</search_keys>
  </display>
</element>


search keys report some error:
Reported Error: "do_query error: SELECT "production_management"."public"."spt_trigger".* FROM "production_management"."public"."spt_trigger" LIMIT 0 "

and x_axis can't work too, still shows the code.

Search Keys should look like sthpw/task?code=TASK00000 etc, with Code.
May be just use expression?
...
<expression>@SOBJECT(sthpw/login)</expression>
<x_axis>login</x_axis>
<y_axis>{@SUM(@GET(loginthpw/snapshot.sthpw/file.st_size))/1024/1024}</y_axis>
...

thank for your reply .
but I find x_axis can't show the column that I input "project", still shows the code for the sType.
please see the attachment

if you have prject column in production_management/main_page, you can add this:

<expression>@SOBJECT(production_management/main_page)</expression>
<x_axis>project</x_axis>

please see attach

I have edit the source py file in:

C:\Program Files\Southpaw\tactic\src\tactic\ui\chart\sobject_chart_wdg.py

in line 288

original:
chart_labels.append( sobject.get_code() ) 
to this:
chart_labels.append( sobject.get_value(my.x_axis))

seems x_axis display correctly.
please see the attachment.
I don't know I am doing the right thing or not. please tell me.

[EricTsuei]

but I still have problems.

about the expression, 
<y_axis>{@SUM(@GET(production_management/main_page.budget))}</y_axis>
<x_axis>project</x_axis>

in my thought, this code should display as,  use the 'project' to sum the total of the budgets. display each project 's total budgets.
but it's not. please see attachment, it just display each of the datas. not combine them.

It would be less complicated if i know your project structure or production_management/main_page stype.
Does it multi project stype? Or porject is just column that you filling yourself?

[EricTsuei]

project is just a column in this page
