could pass UIAxes= matlab.ui.control.UIAxes 's to its member's class instance?

Hi,

I'm using app design to generate ui code and modified to add my class like this:

it will report that cannot call script clearpoints as function .

classdef ds_scopeplot < matlab.apps.AppBase

% Properties that correspond to app components

properties (Access = public)

DataScopeUIFigure matlab.ui.Figure

uartcontrol_panel matlab.ui.container.Panel

PlotButton matlab.ui.control.Button

Switch matlab.ui.control.Switch

SwitchLabel matlab.ui.control.Label

AvailablePortDropDown matlab.ui.control.DropDown

AvailablePortDropDownLabel matlab.ui.control.Label

GridONCheckBox matlab.ui.control.CheckBox

channelselectionEditField matlab.ui.control.EditField

channelselectionEditFieldLabel matlab.ui.control.Label

dataplot_panel matlab.ui.container.Panel

UIAxes matlab.ui.control.UIAxes

Serial_Port_Instance;

end

% Callbacks that handle component events

methods (Access = private)

% Callback function

function ConnectButtonSizeChanged(app, event)

position = app.ConnectButton.Position;

end

function TargetSelectorValueChanged(app, event)

ab = app.AvailablePortDropDown.Value;

app.m_Port_Instance = [];

app.m_Port_Instance = serial_port_user_def(ab,230400);

end

function plot_serial_com_data(app)

app.m_Port_Instance.set_channel_status(0,app.UIAxes);% <--- here will report error about call...

% clearpoints() for cannot call script clearpoints as function.

end

end

end

class serial_port_user_def < handle

%varargin{1} value to check if need clear lines;

%varargin{2} app.UIaxis;

function set_channel_status(sIns,varargin)

if 1 == varargin{1}

sIns.m_plot_handles(size(sIns.m_number_of_opened_channel,2))= animatedline(varargin{2});% expect it works like animatedline(app.UIaxis);

else

%delete this channel data line

if ishandle(sIns.m_plot_handles(openedid))

clearpoints(sIns.m_plot_handles(openedid));

sIns.m_plot_handles(openedid) = [];

%drawnow;

end

end

end

@audo King - what is clearpoints? Is this a function that you have created? Why do you pass sIns.m_plot_handles in one call but no parameters in the other call?
