So i encountered huge memory leak on the free version. Using the trial geared version now and it works great without any memory leak... The trials goes for 10 days and i am pretty much forced to pay 99$ just to fix the issue. Additionally neither the free community version application is working, nor the payment page. Live Charts itself is great(only tested v0 tho, as there is already v2 out), however i made a bad experience as mentioned above.
@@coding_refactor i didnt find the root cause of the memory leak, just noticed there is one. Upgrading to geared Version seems to be fine tho. Even after 10 days i can continue using it without paying.
thanks for this pretty helpful video but i want to ask something we just use datas for the line series but i want to make same thing for the column series for example i am getting data from and csv file and this data has 2 types first one is pressure second one is time how can i show these two things in one chart one of them as a column one of them as a line series Thanks for helping
thank you for this tutorial but i have this errors: System.ArgumentNullException : 'the value cannot be null. parameter name : source' after using this code to fill my gridview code: MySqlCommand sqlCommand = new MySqlCommand(query, db.conn); MySqlDataReader rd = sqlCommand.ExecuteReader(); while (rd.Read()) { //revenue = Convert.ToDouble() Revenue r = new Revenue(); r.Year = Convert.ToInt32(rd["anneeAchat"].ToString()); r.Month = Convert.ToInt32(rd["moisAchat"].ToString()); r.Value = Convert.ToDouble(rd["profit"].ToString()); revenueBindingSource.Add(r); dataGridView1.DataSource = revenueBindingSource; }
is there anyway to use Datetime as AXESX am followin the value of a object every day class { DateTime Day; Float Value; } taking it from a DataTable i called dt that get his values from a database MS SQL keep tellin me cant use a datetime, need for school project ^^
Please could you tell me how to connect it with sql data base not class , i means how to make the live chart take data from the data grid automatically without entering it by user , also thanks for the great effort it is agreat channel
