android - fixed range y axis scale in achartengine -

-

I am making a line chart using achartengine. I am drawing a real time graph and updating the value with a gap of 10 seconds My Y axis is changing on a scale which I do not want because my value always ranges from 10 to 180, so I always want to always specify the y axis. I 

  renderer.setYAxisMin ( 10, 1) trying to work it out; Renderer.setYAxisMax (180, 1);

In addition to this, I want to reduce my X-axis and also the bottom of the screen and the border.

Thank you

AchartEngine Provides an API to set limits for you Y axis And it's right, just you have to use it like this, 

  renderer Set acessimin (-125, 1); Renderer.setYAxisMax (-10, 1);

This is a minor issue but it takes time to recognize, I spent 15 to 30 minutes to understand it. I hope I am not late

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
