Bar Graph legend & x axis

why the legends are showing same colour if i have 1 than 1 data ? if only 1 data then the legend is showing correctly.

how to assign x as each day of month like 1 to 31st july, i need "x" only as date realtime. not as datetime

Change line 3 from

t = datetime;

to

t = linspace(datetime('yesterday'), datetime('tomorrow'), length(InspectionPlan));

For plotting, t needs to be the same size as InspectionPlan. The line above achieves this, but ideally you should probably intialize t so each entry is the date/time of the corresponding entry in InspectionPlan.

% Inspection Demand vs Inspection Executed Trend
InspectionPlan = thingSpeakRead(1421679, 'Fields', 1, 'Numpoints', 100);
t = linspace(datetime('yesterday'), datetime('tomorrow'), length(InspectionPlan));
w1=.5;
hold on
bar(t,InspectionPlan,w1,'FaceColor','r');
InspectionExecuted = thingSpeakRead(1421679, 'Fields', 2, 'Numpoints', 100);
w2=.25;
bar(t,InspectionExecuted,w2,'FaceColor','y');
hold off
grid on
ylabel('Quantity(products)')
legend('InspectionPlan','InspectionExecuted','Location','northwest');
xtickformat('yyyy-MM-dd')
