Creating 2d Plots colors representing log scale weights

Hi everyone,

So I have a 2d plot that represents the geometry of a structure and need to plot wights i calculated on each segment. The weights can range from 0 (could make this eps for plotting) to some unknown quantity. I want to plot the log10 of the weights and adjust the colorbar accordingly. I have attached my two functions that do this. One is part of a class that is called by a plot function.

Main plot function:

    set(0,'DefaultFigureVisible','off')
    temp=[arteryArray.sectionArray,veinArray.sectionArray];
    maxHits=max([temp.hits]);
    maxDose=max([temp.dose]);

    xc=mean(particleArray(:,1));
    yc=mean(particleArray(:,2));
    ang=0:0.01:2*pi; 
    xp=maxElectronRange*cos(ang);
    yp=maxElectronRange*sin(ang);

    fig1=figure('visible','off');
    ax1=gca;
    plot(particleArray(:,1),particleArray(:,2),'x')
    hold on
    %plot(xc+xp,yc+yp);

    title('Hits Plot')
    colormap cool
    caxis([0,maxHits]);
    colorbar;
    fig2=figure('visible','off');
    ax2=gca;
    plot(particleArray(:,1),particleArray(:,2),'x')
    hold on
    %plot(xc+xp,yc+yp);

    title('Dose Plot')
    colormap cool

    caxis(([0,log10(maxDose)]));
    colorbar;
    for i = 1:length(arteryArray)
        %Artery
        arteryArray(i).plotHits(ax1,maxHits)
        arteryArray(i).plotDose(ax2,maxDose)
        %Vein
        veinArray(i).plotHits(ax1,maxHits)
        veinArray(i).plotDose(ax2,maxDose)
    end
    set(0,'DefaultFigureVisible','on')
    figure(fig1)
    hold off
    figure(fig2)
    hold off

Called function in classes: This is where the normalization will happen to the data in the color

   function plotDose(obj,ax,norm)
            meanRadius=mean([obj.sectionArray.outerRadius]);
            for i =1:length(obj.sectionArray)
                startPoint=obj.sectionArray(i).startpoint;
                endPoint=obj.sectionArray(i).endpoint;
                x1 = [startPoint(1);endPoint(1)];
                y1 = [startPoint(2);endPoint(2)];
                z1 = [startPoint(3);endPoint(3)];
                lineweight=2*obj.sectionArray(i).outerRadius/meanRadius;
                cm = colormap; % returns the current color map
                colorID = max(1, sum(log10(obj.sectionArray(i).dose) >...
                        [0:1/length(cm(:,1)):1])); 
                color = cm(colorID, :);
                plot(ax,x1,y1,'Color',color,'LineWidth',lineweight);
            end
        end
