| Which parameter will decide the distance between the RTAlarmIndicator and it's RTBarIndicator? |

| There is no parameter for that because the RTAlarmIndicator position does not use the width of the associated RTBarIndicator as a reference. Instead, the RTAlarmIndicator symbols will always be on the outside edge of the plotting area of the coordinate system the bar is placed in. That way the bar can be the full width of the plotting area and not draw over the alarm indicator symbols. If you want more room between the bar and the alarm indicator symbol, make the bar narrower. |

I don't want more room between the bar and the alarm indicator symbol. I want the alarm indicator symbol to be on the edge of the bar. I copied and paste your code for vertical, and convert it to horizontal, then the alarm indicator symbol is far away from the edge of the bar. I tested by "try and error" to change every possible parameter for many many hours. I just could not make the alarm indicator symbol to be on the edge of the bar.

WE SAID IN THE PREVIOUS POST, THE RTBarIndicator DOES NOT POSITION INSIDE THE PLOT AREA, NEXT TO THE BAR. IT IS POSITIONED OUTSIDE OF THE PLOT AREA, NEXT TO THE MAXIMUM EDGE.
We have no idea why you spent many hours, using trial and error to accomplish this. You should have spent 10 minutes creating a simple example program that demonstrated your problem. You should be able to start with our BarApplication1 example program. It displays a single RTBarIndicator, next to an RTAlarmIndicator. The alarm indicator is right up against the bar indicator, because the bar has a width of 1.0, and the pTransform1 Cartesian coordinate system the bar is placed has been scaled to a width of 1.0.
We can only guess that you have scaled your bar coordinate system for (0-100, 0-100), but your bar width is only 50, filling only half the plot area. If you want the bar indicator to fill the entire height of the plot area, you must use a bar width of 100, given your scale.
DO NOT POST LARGE CODE BLOCKS LIKE YOU DID - IT MAKES THE THREAD UNREADABLE. IF YOU HAVE TO POST MORE THAN 20-30 LINES, YOU HAVE NOT ISOLATED THE PROBLEM ENOUGH. IF WE THINK WE NEED MORE CODE WE WILL ASK THAT YOU SEND US A COMPLETE EXAMPLE PROGRAM.

The example that you mentioned does not help. The example is a vertical bar. I could not convert it to a horizontal bar by simply replacing ChartObj.VERT_DIR to ChartObj.HORIZ_DIR, I have to do too many other detail replacing jobs.
Because I could not find an example of horizontal bar with indicator on the edge in your example set. I used your example of
vertical bar with indicator on the edge of the bar, and convert it to a horizontal bar. It is not just a simple replacement of ChartObj.VERT_DIR by ChartObj.HORIZ_DIR. Many other tedious jobs were involved. While these tedious work fixed many other issues, I am not able to fix the problem of the indicator far away from the bar.
I followed your instruction here to re-exam my example. I assume this line of the code "pTransform1 = new CartesianCoordinates(0.0, 0.0, 100.0, 100.0);" is what you mean the coordinate system of 0 - 100, and this line of the code "baralarms.setLocation(50.0, 50.0);" is what you mean "the bar width is only 50". So I change "baralarms.setLocation(50.0, 50.0);" to "baralarms.setLocation(100.0, 100.0);" I found that it has the same effect (no change in the graph). In fact, I can simply delete this line "baralarms.setLocation(50.0, 50.0);" to get the same effect; or set "baralarms.setLocation(0.0, 0.0);" to get the same effect.

I eventually found that I should make the variable xyz to be 100 in the following instanciation:
new RTBarIndicator(pTransform1, PIDProcessItems, xyz, barbase,
attrib1, barjust, barorient); |

Since your xyz parameter is the bar width of the RTBarIndicator, what you did is exactly what we said to do a couple of week ago: "If you want the bar indicator to fill the entire height of the plot area, you must use a bar width of 100, given your scale."
