tick alignment/ position/ rotation in charts

[Srirama Bhamidipati]

Hi

I am displaying a date as a x-axis tick label in the following format in 2018-Jun-12. However it appears that this is too long and no further tick labels are shown except the first. So I am wondering if it is possible to rotate the tick label ? Also my legend is at the bottom of the chart, Can I change the position of the legend?

thank you

Srirama

Rehi :)

In fact, it is not that the date is too long. The problem is that he is trying to put labels for the missed ticks (the one where the chart is not displayed), even if the chart serie itself (the line) does not use them. Because the default size of the x serie is 1 (tick).

Solution: change the tick size.

For example if the tick is one hour: x_tick_unit:24

If your tick is one minute x_tick_unit:24*60

For example

chart "mode share" type:series 

x_tick_unit:24

x_serie_labels: string(current_date, "dd MMMM yyyy")

{

data "bike" value:ln(cycle+1) color:#blue  thickness:2 marker:true;

}

You can also put more if you want to display the legend every 2 or 3 points!

But you are right, it would be nice to have also some orientation feature... Some improvement idea for the chart!

hi Philippe,

The tick unit is clear to me now, thank you. I now use step minute. But I could not resolve to show the tick labels. Please See picture and code 

display "modal share" type:java2D refresh: every(1#day) {

chart "mode share" type:series 

style:spline

//y_range:{0,1000}

x_serie_labels: string(current_date,"dd MMMM yyyy") 

x_tick_unit:24*60

series_label_position: xaxis

{

data "bike" value:length(list(inhabitants) where (each.value_mode_actual = 1)) color:#blue  thickness:2 marker:false;

}

}

Hi Philippe,

This is still not resolved for me. I do not see the dates as tick-labels :( 

Srirama

[Philippe Caillou]

Hi Srirama,

The issue is still the alignement of the tick and the points. To see this, you juste have to put a marker, the points have to be on the tick lines to be able to display a label.

The problem seems to be that the first cycle is 0, and the every(1#day) is true for 1, 25, 49 and not 0, 24, 48.

If you replace the test by ((current_date.hour)=0), it works for me (with a cycle by hour and tick_unit=24). So I supposte    ((current_date.hour)=0 and ) (current_date.minute)=0) for you.

This is however a workaround. You should be able to specify the x_serie, for example x_serie=ceil(cycle/24/60), but I checked, it doesn't work because it still wants to create the x_serie for the cycles it is not refreshed... I will post an issue for that!

Tell me anyway if the first solution does not work for you!

Hi Philippe,

I am not sure I understand you completely. I tried your suggestion of current_date.hour and current_date.minute as the condition, but no success. 

Are you sure it is 1,25,49 instead of 0,24,48? My step is one minute and I am using tick as follows:

display "Modal share" type:java2D refresh: ((current_date.hour) = 0 and (current_date.minute) = 0) {

 

chart "mode share" type:series 

style:spline

//y_range:{0,1000}

x_serie_labels: string(current_date,"dd MMMM yyyy") 

x_tick_unit:24*60

series_label_position: xaxis

{

data "bike" value:length(list(inhabitants) where (each.value_mode_actual = 1)) color:#indigo  thickness:2 marker:true;

data "walk" value:length(list(inhabitants) where (each.value_mode_actual = 2)) color:#deepskyblue  thickness:2 marker:true;

data "pt" value:length(list(inhabitants) where (each.value_mode_actual = 3)) color:#mediumvioletred  thickness:2 marker:true;

data "car" value:length(list(inhabitants) where (each.value_mode_actual = 4)) color:#maroon  thickness:2 marker:true;

data "" value:length(list(inhabitants) where (each.value_mode_actual = 1)) color:rgb(#indigo,0.12)  thickness:27 marker:true;

}

}

Hi Srirama,

Ok, I just tried with a minute level time, and it work with:

refresh: ((current_date.hour)=0 and (current_date.minute)=59) 

You can see that otherwise the tick and markers are not aligned

Now I just have to understand why and modify the x_serie default behavior so that it doesn't put value when it is not refreshed :)

In the meantime, can you try that? (I know, this is a little ugly...)

Hi Philippe,

No success, but if I understand you correctly: I have to align tick mark with markers to have the desired result?

I am on 5th July 2018 Gama Standalone on windows 7.

[Philippe Caillou]

Yes, that’s it (the x_series_label is only set when there is a refresh, so a marker…).

It is strange it doesn’t work for you.

Here is my complete code (mostly copy/past from yours):

 

 

model NewModel

 

global

{

       float step <- 1 #minute;

}            

 

/* Insert your model definition here */

experiment test type:gui

{

             

              output {

display "modal share" type:java2D  refresh: ((current_date.hour)=0 and (current_date.minute)=59)

{

             

                                          chart "mode share" type:series

                                          x_tick_unit:24*60

                                          x_serie_labels: string(current_date, "dd MMMM yyyy")

                                          {

                                                         data "bike" value:ln(cycle+1) color:#blue  thickness:2 marker:true;

                                                        

                                          }

                                         

 

              }

}            

}

Hi Philippe,

Just to cross check, I draw a line at each tick and also a marker on the series, Is this what you mean?  If this is what you mean, then I do not get the tick label with a date :(

I only changed the refresh condition as you can see in my previous mail., your condition is just commented out

display "Mode share" type:java2D refresh:cycle > 0 and every(#day){// ((current_date.hour) = 0 and (current_date.minute) = 59) {

I think your comment on 1,25,49 is correct; because chart first plots init values, then it plots cycle 0 and then there is cycle  24, so the init and cycle 0 slightly alter the tick marks
