Human Heat Map Designed by the JMP Custom Map Creator - (2023-US-PO-1385)

Disease often shows a predilection for specific site locations. To demonstrate the body regions involved, researchers may use infographics or tables. While tables may be more descriptive and universal to any statistical software, heat maps rapidly communicate disease involvement across a cohort. At our institution, software to portray data into the confines of a human body is not readily available. Additionally, we needed the human body to be segmented into specific regions. While a graphic editor can be used, it is labor intensive, limits generalizability, and cannot be repeated with different data sets.

 

To create a scalable solution, we used the Custom Map Creator in JMP, an add-in to Graph Builder that allows users to create custom shapes. With this program, we outlined a human body, created anatomic regions, and colored each region based on the percentage of occurrence. The selected color range is scaled to directly correlate with the data. Each anatomical subunit is then filled and shaded by the data in the respective column. Heat maps provide easy interpretation and clearly portray the most involved areas for rapid communication to readers.

 

 

 

Today,  I  want  to  give  a  little presentation  about

 

using  the  JMP  Custom  Map  Creator

and  how  we use  that  to  develop  a  human  heat  map.

I'd  like  to  give  a  shout out  to  my  mentor,

Dr.  Benjamin  Caffender,  who  helped push  this  project  along.

A  little  bit  about  the  Custom  App  creator,

it  allows  you  to  create  custom  shapes that  can  be  displayed  in  Graph  Builder.

What  this  allows  you  to  do  is  to

take  statistical  data  and  percentages in  particular,  and  present  them

in  a  color-coordinated  and color-referenced  presentation.

The  way  that  this  is  used,

it  comes  with  some  built-in  maps of  the  United  States

or different  places  in  the  world, is  to  be  like,  oh,  in  this  state,

this  percentage  of  whatever is  taking  place  is  occurring.

Gives  you  that  heat  map  approach,

but  it  also  allows  you  to  create different  objects  as  well.

For  us,  this  was  a  dermatology  project, so  we  had  cutaneous  disease,

and  so  we  wanted to  show  lesion  involvement

on  what  part  of  the  bodies were  affected  by  the  disease.

So  we  had  face,  90 %, we  had  scalp,  but  just  under  20 %.

That  thing, we  wanted  to  show  this  dynamically.

We  ran  into  what's  the  best way  to  go  about  it.

We  did  some  digging.

We  found  this  custom app  creator  to  do  that.

What  we  did  is  we  took  an  outline  of  an image,  and  you  can  see  all  these  dots.

We  went  in  and  we  traced  this  image

and  created  our  different  body  areas,

and  JMP  will  set those  into  specific  shapes

where  you  can  input  data that  will  appear  in  those  areas.

You  can  take  whatever  picture  you  want.

This  is  is  an  example  of  one  that  we  used.

Then  that  data  will  get incorporated  into  those  areas.

So  you  can  see  over on  the  left  of  our  image,

really  to  show  the  face  has  significant involvement  with  the  darker  red,

and  that's  correlated  up  with the  90 %  involvement

versus  lighter  areas  such as  the  trunk  or  upper  extremities.

But  the  custom  upgrade lets  you  create  those  areas

and  then  put  those  inputs and  put  those  percentages  in  very  easily.

Rather  than  me  talking  about  it,  I'd  like to  show  you  a  little  demo  of  how  it  works,

and  we  will get  going  from  there.

I  already  have  JMP  open.

Once  you  install  this  add-in,  it's

going  to  add-in  map  shapes and  then  custom  map  creator.

We  put  custom  map  creator, and  we  get  these

different  data  tables  that  pop  up

as well  as  our  map  creator  itself.

So  what  you  do  is  you can  paste  an  image  in.

I  have  a  file  over  here  that  I will  just  drag  and  drop  in.

You  can  copy  paste  however  it  may  be.

You  can  adjust  and  zoom  and  that  thing to  get  it  exactly  how  you  want.

Give  it  a  name.

Now  you  start  drawing, you  start  tracing.

I'll  just  quickly  click  through  here.

That's  one  shape. We  hit  Next  Shape.

You  can  change  the  names  of  your shape  to  whatever  it  may  be.

When  we  were  using  it, we  had  different  body  areas.

If  you  look  over  on  the  right  at  the  data tables  up  here

in  this  table,  this  example  X,  Y, we're  seeing  the  different,

the  very  specific  data  points  or dots  that  are  being  graphed.

Over  here,  we're  having these  shape  IDs  be  placed.

You  can  see  up  here, I'm  working  on  shape  five.

You  hit  Next  Shape.

As  you  put  that  in, you  get  these  next  shapes.

These  are  linked  between these  two  data  tables.

Now  we  have,  let's  say,

I've  finished  my  image, I  have  everything  graphed  out,

you  can  hit  finish, and  that  will  just  save  it,  or

you  can  also  finish  with  random  data, which  I  think  is  an  easy  way.

It's  an  easy  wayto  show  it,

but  also  just  to  actually  have the  data  show  up  in  the  right  place.

Hit  open.

Now  we  have...

This  is  our...

This  is  our  graph.

We  can  see  this  data they  gave  us  over  here,  shape  one,

I'll  just  drop  this  down  to  one  over to  shape  five  we'll  put  that  at  100.

You  can  see  over  here,  shape  five,  100,

this  is  our  red and  has  the  most  involvement.

Down  here,  shape  one,

I  guess  we  have  a  couple  on  the  lower and  this  is  the  darker  blue.

But  you're  able  to  get that  stratification.

So  what  you  can  do  is  you  can  either have  your  own  data  table,

or  you  can  just  put  in  your  own  data  into these  shapes  as  well,

and  it  will  adjust  in  real  time.

What's  really  nice  about  this  add-in

is  you  can  go  right here  and  you  can  change  these  gradients.

Right  now  we  have  a  red  to  blue.

You  can  change  it  from  this  yellow  to  red.

We  can  have  that  higher  volume with  the  darker  colors  and  less

involvement  with  the  lighter  colors really  easily.

The  two  big  things  as  you're  doing  this

that  are  important  to  know  is  if  this  is your  own  data  table,  this  shape,

this  name  column and  the  column  properties  and  map  role,

we  see  here  this  map  name  data  table is  connected  to  our  example  name. Jmp,

which  that  is  one  of...

That  is  this  file  over  here.

It  is  super  important that  those  have  to  be  linked.

If  you  hit  generate  random  data, it  does  it  for  you.

If  you  have  your  own  data  table, you  have  to  manually  set  that.

But  what  you'll  notice  is  if  you  manually create  your  own  data  table,

here  this  shape  1,2,3,4,5  matches  up perfectly  with  shape  1,2,3,4,5  here.

Those  names  have  to  be  exact and  those  roles  have  to  be  exact.

If  you  do  that,  then  you  can have  this  data  pop  up  really  easily.

You  can  also  get  these  data  tables through  Graph  Builder  as  well.

But  yeah,  that's  just  a  quick overview  of  how  to  use  this  add-in.

It's  very  versatile.

Like  I  said,  we're  able to  use  it  for  our  project.

Yeah,  I  hope  this  gave  you  just a  brief  little  bit  of  guidance  on  that.

I've  uploaded  some instructions  on  how  to  use  this  as  well,

which  you  can  also  find.

But  I  hope  you  have  a  great  day

and  a  great  rest  of  other presentation  to  get  to  watch.
